About Trek

TREK is the UK's fastest-growing protein bar brand and the number 2 protein bar in the market, with brand value hitting £41.5 million following five consecutive years of double-digit growth. Part of the Lotus Bakeries Group and produced by Natural Balance Foods in Buckinghamshire, TREK has transformed from a challenger brand into a category leader. TREK protein flapjacks are the brand's signature product - a "British classic, revolutionised!" Made with gluten-free oats and soya protein crunchies, each 50g bar delivers 9g of plant-based protein alongside carbohydrates for sustained energy. All TREK products are 100% vegan, gluten-free, and high in natural fibre, making them ideal for health-conscious consumers. Popular flavours include Cocoa Oat, Peanut Butter, Salted Caramel, and White Chocolate Raspberry. In 2025, TREK launched the highly successful Biscoff® Protein Flapjack (now the number 1 new product in cereal bars) and a new High Protein Low Sugar range using only natural ingredients. The brand is also a partner of RunThrough, the UK's largest running events programme. Use Grocefully to compare TREK protein flapjack prices across Tesco, Sainsbury's, Asda, and other UK supermarkets to find the best deals on your favourite vegan protein snacks.

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. We handle the complexity of split orders so you save money without any extra effort.

Our users save an average of 25-30% on their total grocery bill. For a typical £100 weekly shop, that's £20-25 in savings even after our 5% service fee. The exact amount depends on your shopping habits and the products you buy.

We currently support Tesco, ASDA, Sainsbury's, Morrisons, Waitrose, and Iceland. We're constantly adding new stores and will notify you when more become available.

Grocefully is available wherever the supported supermarkets deliver. Simply enter your postcode when you sign up to check availability in your area.

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 an average of 25-30% per shop. Even after the 5% service fee, you're still saving 20-25% on average. For a £100 shop, you'd save £25-30 and pay £5 in fees, netting you £20-25 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.

Refunds are processed according to each supermarket's policy. If you're not satisfied with your savings, contact our support team - we offer a money-back guarantee on our service fee.

Our customer support team is here to help resolve any issues. We work directly with the supermarkets to ensure quick resolution of any problems.
