I went today - and spent £190...
Bought meat, sausages, fish, toilet rolls, kitchen rolls, water, eggs, cetaphil cleanser and moisturiser, toothpaste,
ermmmmm
rotisserie chicken which we had for dinner this evening.
pens for son for school. yogurt, cheese, coffee, bread, gin (Bombay sapphire, 1 lite - I think was about £17? )
and more.
I went with my mum, who bought me a new handbag for xmas - I have to try and forget what it looks like now. 
Washing powder is excellent, the loo rolls are fab, as are the kitchen rolls.
oh, and the big cakes are brilliant.
About £8 for a massive chocolate fudge cake - carrot cake is my fave though :)
enjoy!
VAT is payable on non food items. both prices are on the display label. trade members do pay the vat - I guess they then can claim back whatever they sell? I am a trade member, but not in the buy and sell business. we shop at Costco for personal shopping.
