I went to Michael's Craft Store to buy craft/organizer shelves that they had on their website. When I saw the quality and price of the units, I changed my mind and shopped elsewhere. I did buy some art canvas boards though.
The staff, when you can find them, are usually pleasant, but they don't seem to be very knowledgeable about their store or supplies. Further training would be a great idea.
It would also be nice if they acknowledged you when you walked in the door. Even if they are serving another customer, a nice "Hi, Welcome to Michael's" would be a good beginning. The only stores I know that say "Hi" to everyone when they enter their store is Urban Barn and 7-11. That's my favorite thing about those stores, they acknowledge your presence from the very beginning.
Michael's is a good store for most art supplies.
