Let’s get you saving money while eating better than ever.

Why Vegan Meals Can Actually Be Cheaper

There’s a myth that going vegan is expensive—mainly because of pricey meat substitutes, imported superfoods, or “health store” branding. But the foundation of a plant-based diet—beans, lentils, whole grains, seasonal vegetables, and fruits—is some of the most affordable food you can buy.

For example:

1kg dried lentils can cost as little as £1.60 and make 6–8 hearty meals.
A bag of oats for £1.20 can provide breakfasts for two weeks.
Seasonal vegetables (think carrots, potatoes, cabbage) can cost under £1 per kilo.

The challenge is that prices vary dramatically between stores. A tin of chickpeas could be 39p in one supermarket and 75p in another. Multiply that difference across a 20-item shopping list, and you could be overpaying £10–£20 every single week.

This is where Cheapify.app’s smart grocery price comparison comes in.

How Cheapify.app Helps You Save Big

Cheapify.app takes your grocery list and instantly shows you the cheapest combination of stores to buy everything from.

Here’s how it works:

Add your grocery list – Enter your weekly items or pick from suggested vegan staples.
See instant price comparisons – Cheapify scans prices from major UK supermarkets like Tesco, Sainsbury’s, Aldi, Asda, Lidl, Morrisons, and more.
Get the cheapest store mix – You’ll see exactly which store has each item for the lowest price.
Save or adjust your list – If you’re flexible, swap items for even cheaper alternatives.

For example, a week’s worth of plant-based groceries might cost £48 buying everything from one store. But by following Cheapify’s suggestions and picking certain items from cheaper stores, you could pay £28–£32 instead—a saving of up to £20 per week.

The £20 a Week Saving Plan

If your goal is to save £20 a week, here’s a simple structure:

Step 1: Audit your current spending Write down your regular vegan grocery list and total cost.

Step 2: Run it through Cheapify.app Let it find the cheapest store for each item.

Step 3: Swap where possible If you’re not tied to a brand, try cheaper alternatives Cheapify suggests.

Step 4: Meal plan around offers If broccoli is on offer this week, plan 2–3 meals with it.

Step 5: Track your savings By the end of the month, you’ll see the difference—£80 or more in your pocket.

Real-Life Example

Let’s take a sample weekly vegan shop for two people:

Original one-store price (Tesco example): £48.20

Cheapify-optimised price (multi-store mix): £29.75

Chickpeas: 39p (Aldi) instead of 75p (Tesco)
Red lentils: £1.59 (Asda) instead of £2.10 (Tesco)
Bananas: 69p/kg (Lidl) instead of £1.05/kg (Tesco)
Frozen spinach: 99p (Aldi) instead of £1.50 (Sainsbury’s)
Oats: £1.20 (Morrisons) instead of £1.65 (Tesco)

That’s £18.45 saved in one week—without sacrificing a single meal.

Why This Works for Long-Term Success

The key to sustainable savings is consistency. Cheapify makes it easy to stick to the habit because you’re not manually checking dozens of websites or wandering through four stores hoping for deals.
