Memory Stick Selection

I went to Superstore the other day to find out if they have a Canon memory stick. My memory stick for my Canon digital camera is finished and I need a new one for my photography project.
I asked the sales clerk if they have Canon brand but she said that they only carry the President's Choice brand name. She's helpful anyways in directing us to Staples.

At Staples, they don't have the Canon brand but it turned out I can have other brand names to use in my digital camera as long as it fits in. The Sony memory stick that my husband bought for my other camera is worth more than a hundred dollars. Other memory sticks are worth more over than 50 dollars plus tax of course. GST and PST! Looking for the Canon memory stick which they don't have at that time or they don't carry it..thinking, do I have to go to Zellers? Or go to Future Shop and The Source to get it when there's another brand that is worth more than 50 dollars for 2GB but it's on sale on that particular day. Going to other shopping arcade to find what I'm looking for would be a waste of our vehicle's gasoline when there's already a good deal here and if it works on my camera then what's the fuzz right?

So, my husband and I bought it but I warned the sales clerk that if it didn't work on our camera I will have to return it. And it did worked alright. Thanks to Staples for the discount!
