I love Costco! Although you have to be careful that it's not always the cheapest to get certain products but I really appreciate the excellent quality of most of their products.
I've recently tried the Opera cake and i wasn't impressed at all but still it was $10 cheaper than my favorite pastry shop.
The key for me to get the best deals from Costco is googling the big (or small!) purchases before getting them..which always tells me if i'm getting the best price and if the item is really worth it.

This is one of my favorite stores to shop at. You can find great deals on groceries helping you pinch your pennies plus you never know what you will find there. I just got a great kids picnic table that folds and is made by lifetime for $50 and this table would be $100 at other stores. Its all luck of the draw for good deals here but its well worth the look.

What can a person say. Love love this store, great selections, great products and amazing prices! love Costco!

I love Costco ! They literally sell everything, and they have great prices! But my fave part is throughout the hole place they fave sample stands where you can actually go around and try different food, drink or product samples!
