Hi Steve
Where are you located?
Just in case you are unaware, Costco are a huge American wholesale group, where you can buy almost anything a bit like Macro only a 100 times better and they only deal in good quality merchandise often at discounted rates.
I have been a Trade Member for 10 years now and it's well worth it.Trouble is taking the missus with you, they spend a small fortune in there.
You would know if you had one close by but even if you have to travel a bit it's worth it to become a member. Go to www.costco.co.uk to obtain further info.
