FE has the lowest prices for designer brand frames like RayBan and sunglasses online and some great deals on specialist lenses like transitions or tints. I bought a pair of RayBan frames which cost over £200 on the highstreet for just £63 on FE website, well pleased! They also do a fantastic offer: 25% off for you, and any people you refer, making their prices even lower. There's no free delivery but they offer a range of delivery options starting from just £3.99 for 2 day delivery. They also deliver to other countries besides the UK. Delivery is often faster than big highstreet opticians, with fashion lenses coming next day, and prescription glasses in 5-9 days.
