Michael's really deserves one star or five, depending on the day. It somehow manages to be exactly what you need or your worst nightmare.
If you were to walk in without a plan, you would encounter plastic trees (the kind that you see out by the curb on garbage days) for over $200 and picture frames you would find at the dollarama for $29.99.
You might also search the entire store for someone to help you and find no one. In fact, that is pretty likely.
On the flip side, if you keep up with their promotions and surrender your e mail address for coupons, you can structure things in a way where you actually make it out of the store with your wallet and maybe even find a deal.
One other small thing to note here is that the ladies working behind the counter at the register are actually helpful. If no one is waiting, they seem happy enough to answer questions and even leave their post to help.
