FAQs

Grocefully is a smart grocery shopping app that automatically compares prices across all major UK supermarkets (Tesco, ASDA, Sainsbury's, Morrisons, etc.) and helps you buy from the cheapest stores. When you place an order, you authorise Grocefully to act as your purchasing agent — we place orders on your behalf at each supermarket, so you get the best prices without the hassle of managing multiple orders yourself.

Still confused?Contact us

Our AI scans real-time prices from all supported supermarkets every time you shop. It finds exact matches or suitable alternatives for each item on your list, then automatically selects the cheapest option while considering delivery fees and minimum order requirements.

You can set brand preferences for any item. If you prefer specific brands, Grocefully will only compare prices for those brands. You can also allow substitutions for some items while keeping others fixed.

Grocefully shows you available delivery slots from each store and helps coordinate them. We optimize to get you the most convenient delivery times while maintaining the best prices.

Yes! You can link your loyalty cards from each supermarket and continue earning points on all your purchases. We'll automatically apply any available discounts.

We charge a simple 5% service fee on your total order value. For example, if your groceries cost £100, you'll pay £5 as a service fee. This covers our costs for finding you the best prices, handling multiple orders, and providing customer support.

Our users save up to 30% per shop. Even after the 5% service fee, you're still saving up to 25% on average. For a £100 shop, you could save up to £30 and pay £5 in fees, netting you up to £25 in savings!

The service fee is automatically calculated and shown before you complete your order. It's added to your total, so you only make one payment. No hidden charges or surprises.

Yes! Grocefully is completely free to download and use. You only pay the 5% service fee when you place an order. Browse, compare prices, and create shopping lists as much as you want without any charges.

No hidden fees! You pay the grocery prices (same as shopping directly), the stores' delivery fees (if any), and our 5% service fee. That's it. We believe in complete transparency.

If you're not happy with your savings, contact our support team. We'll review your order and if we didn't save you money (after accounting for our fee), we'll refund the service fee. Your satisfaction is our priority.

Yes, you can modify orders up until the supermarket's cut-off time (usually a few hours before delivery). Any changes are automatically synced across all your orders.

If an item is out of stock, we'll automatically find the next cheapest option from another store or suggest a suitable replacement. You can set preferences for how you want us to handle substitutions.

Since you're purchasing directly from each supermarket (with Grocefully acting as your agent), refunds for grocery items are subject to each supermarket's policies. For issues with groceries, we'll coordinate with the relevant supermarket on your behalf. For our service fee, we offer a money-back guarantee if we didn't save you money.

Our customer support team is here to help resolve any issues. We'll coordinate with the relevant supermarket on your behalf to get the issue resolved as quickly as possible.
