A great Costco with good staff.
Only negatives: Ohio doesn't allow a liquor store, and 7.75% Cuyahoga county sales tax (July 2011).
The fuel island typically has better prices than even other area Costco's due to fuel sales competition in Strongsville.
The location is great, right off I-71, and it's relatively easy to pop in off of SR-82.
Location to South Park Center mall makes it great to hit other stores at the same time.
This Costco has an excellent florist with great flower selection. They lack on some high end wines that other Costco's have, and their snack bar is typical of the US Costcos that lack things like sandwiches, burgers and fries that Costcos outside the US have.
I love their self checkout, but if you have an item that's easier scanned by the staff they're pleasant and a delight to shop with.
