Is Online Supermarket Delivery Actually Cheaper in 2026?

Online grocery shopping used to be an easy win. No wandering round aisles, fewer impulse buys, and often decent value once delivery was factored in.

In 2026, it’s more complicated.

Between delivery fees, minimum spends, loyalty pricing, saver passes and personalised offers, the cheapest online supermarket depends far more on how you shop than where you shop.

I’ve been ordering groceries online for nearly 15 years. Not because I love technology — but because I hate walking around supermarkets looking lost. Over that time, one thing has become clear: headline prices rarely reflect what people actually pay.

So instead of asking “Which supermarket is cheapest?”, this guide answers a more useful question:

When does online supermarket delivery actually make sense — and how do you avoid overpaying?

Aldi isn’t an online option anymore

Let’s clear this up straight away.

Aldi is still the cheapest supermarket in-store. That hasn’t changed.

But in 2026, Aldi is effectively offline.

There’s no:
• Home delivery
• Click & collect
• Official online grocery ordering

Any “online Aldi shopping” now relies on third-party runner or concierge apps, which add hefty mark-ups. That usually makes Aldi one of the most expensive ways to shop online.

So while Aldi often tops supermarket price comparisons, it simply isn’t part of the online delivery conversation anymore.

Delivery charges: where online shops quietly get expensive

Delivery fees are where online shopping often stops being good value.

Most supermarkets now use dynamic pricing, which means costs change depending on time, demand and basket size. In practice, this is what you’re dealing with in 2026:

• Delivery fees usually range from £1 to £7
• Orders under £40–£50 often trigger £3–£7 small basket surcharges
• Saver passes matter more than headline delivery prices

In broad terms:

• Iceland remains the standout for free delivery over £40
• Morrisons is often strong value if you’re flexible with slots
• Tesco and Sainsbury’s are competitive if you use saver passes
• Waitrose can be cheaper than expected outside peak times

If you shop online more than twice a month, a delivery saver usually pays for itself very quickly.

A baseline basket comparison (no loyalty, no offers)

To see where value starts, I priced the same basket of 17 everyday household items across major supermarkets.

This comparison excludes:
• Loyalty prices
• Personalised offers
• Multibuys

It’s not what most people actually pay, but it shows the underlying pricing.

Basket totals:

Aldi – £40.99 (in-store only)
Morrisons – £44.46
Asda – £44.68
Tesco – £46.61
Sainsbury’s – £48.66
Waitrose – £55.39
Co-op – £56.44
Iceland – £61.24

Once Aldi is removed, Morrisons comes out strongest on baseline online pricing, with Asda, Tesco and Sainsbury’s close behind.

But this is where modern online shopping flips.

The loyalty pricing “non-member tax”

This is the biggest shift in recent years — and the reason many supermarket comparisons are now misleading.

In 2026, loyalty prices aren’t optional. They are the real prices.

At Tesco and Sainsbury’s:
• Shopping without a Clubcard or Nectar card can cost £30–£50 more on a big shop
• Personalised offers are based on what you actually buy
• Two households can pay very different totals for the same basket

Recent Which? comparisons show Tesco, once Clubcard prices are applied, can undercut rivals like Asda on large shops.

If you refuse to use loyalty cards, you’re effectively paying a non-member tax.

Why Iceland can cost more than Waitrose online

This catches a lot of people out.

Iceland is cheap for frozen staples — that hasn’t changed.

But Iceland is heavily brand-led in other categories. Once you add branded household cleaners, soft drinks and ambient food, costs rise quickly.

Waitrose, on the other hand, has a surprisingly competitive Essential own-brand range. On an own-brand-heavy shop, Waitrose can undercut a branded Iceland basket.

Reputation doesn’t always match reality.

Which option is cheapest for your type of shop?

Rather than chasing a single “winner”, this is how online shopping tends to shake out in practice:

Shopping situation | Best option | Why
Big weekly online shop | Morrisons or Tesco (with loyalty) | Strong own-brand pricing and saver passes keep costs down
Regular online orders | Tesco or Sainsbury’s with a delivery pass | Loyalty pricing and personalised offers add up over time
Small top-up shops | Avoid delivery where possible | Small basket surcharges can add 20%+
Frozen food focus | Iceland | Free delivery over £40 and strong frozen range
Bulk cupboard stock-ups | Discount food sites | Best value for branded goods and treats

This is where most savings are actually made.

Which online shopping option is cheapest in practice?

The “ghost basket” trick that really works

One of the easiest ways to save money online is keeping a running basket in your supermarket app all week.

Add items as you run out.
Wait until you hit the minimum spend.
Avoid ordering when you’re hungry or rushed.

It helps you avoid:
• Small basket surcharges
• Impulse buys
• Panic top-up orders

It’s dull — but it works.

Stack savings with receipt cashback apps

This is an easy win many people ignore.

By uploading photos of supermarket receipts, you can earn cash or Amazon vouchers throughout the year. With very little effort, £100 a year is realistic.

Some apps even refund 100% of selected items, letting you stack savings on top of your normal shop.

I’ve rounded up the best options in my receipt scanning apps guide and the best cashback apps.

Cheap online food shopping outside supermarkets

You don’t have to rely on supermarkets at all.

I’ve also cut my food bill by using discount food sites that sell items close to — or just past — their Best Before date. That doesn’t mean unsafe food. It simply means shorter shelf life, which is why the prices are so much lower.

Two sites worth checking if you’re happy planning ahead are Approved Food and Low Price Food. You’ll often find branded groceries and household items at prices supermarkets can’t touch.

It’s not a replacement for a weekly shop, but it works brilliantly for stocking up on cupboard food, drinks and treats — and you’re helping reduce food waste at the same time.

So… is online supermarket delivery cheaper in 2026?

Sometimes — but only if you’re smart about it.

There’s no single “cheapest online supermarket” anymore.

The cheapest option depends on:
• How often you shop
• Whether you use loyalty pricing
• Delivery vs click & collect
• Whether you stack cashback and saver passes

Aldi is cheapest in-store, but irrelevant online.
Morrisons offers strong all-round online value.
Tesco and Sainsbury’s can be cheapest if you use loyalty pricing properly.

The real savings come from how you shop, not just where you shop.
