I use this place for stocking up on business supplies as well as getting the more bulk-type stuff for home. They have a fantastic return policy - I ordered two different kinds of office chairs online and put them together at home, didn't like one of them and was able to return it 'built' without any problem. I have the Exec. Membership which means I get 2% off all purchases back as an annual cheque, more on the (already cheaper) gas - so I hardly pay anything for membership at the end of the year.
I just tried out the tire centre this week, and although the guys are great, it's very difficult to get anyone to answer the phone in that department. Combine this with the fact that you can't book a service appointment on the weekend (first come first served) and my recent experience of being here 15 mins before they were due to open on Sunday and STILL being told I had 90 minute wait means that I can't give them more than 4 stars...
