Costco Wholesale at 100 Veterans Way, Warminster, Pennsylvania.

Its a members only shopping, before you checkout you have to swipe your membership card. And if you are not purchasing form your nearby Costco, they will not accept card payment. You have pay as cash.
Food quality is good , you can find almost everything. Electronic items will have minimum of 10% difference from outside delear. Most of things are in bulk or bundle. It doesn't make sense to purchase for day or 2. You have buy at least for a week worth goods.
There wine .......
It's a world in itself. They have everything we can imagine about wine.

I LOVE Costco. A few years back we made the switch from Sam's Club because I wanted to support a business that actually treats its employees well. The prices are comparable to other wholesale-style stores, but Costco will mail out a booklet to members about monthly sales on items. I highly suggest always looking through those to find the best deal.

The employees are always warm, friendly, and helpful. The cafe also has standard Costco food ($1.50 hot dog/soda combo, $2 pizza slice, etc.). And as always, they have a generous return policy. (Please don't abuse it, it's fantastic- no receipt needed, satisfaction guaranteed within a month for large appliances, etc.).

I've never had a problem with anything here in the few years I've been a member, and I've always enjoyed my shopping trips here. Highly recommend!
