My experience here is mostly buying a Dlink router that was on sale, mouse and Canon ink catridges. Place is huge. Parking is plentiful. When I ask for help, there is usually a staff who is able to help me out. Not a lot of staff people on the floor so the place reminds me of Walmart in some way. I haven't had a bad experience here.
Note that if you return an item, they refund you your purchase price but charge a restocking fee. Do ask when you buy something there.
