What Kate said.
Been a member for about 6 or 7 yrs now and buy similar items to Kate. Excellent quality, unbeatable money back guarantee if not satisfied. We bought our new bed from them online. We are now 'executive' members and get 2% cashback on our annual spend in the form of vouchers. It's great for buying unusual and useful pressies etc. certain things are really good value - all magazines are 20% off retail price, Huggies nappies are cheap if this is of interest to you. Appliances, washers, dryers etc often at very good prices and no quibble guarantee. (If you ever have cause to return anything, you don't even need your receipt, as they can find it in your purchase
history). I share my membership with my father in law (he has my 'spouse' card, as I always take Mr L with me when I go).
You can still get a guest pass to have a look round and decide if it's worth you joining, but they won't let you buy anything until you join. I believe you can give back your membership at any time and they will refund the unused portion of the membership fee, so nothing to lose really.
