Sales on today, went to store on Marine Drive tried to buy couple SD cards, went in right after store openned. There were only two customers, the other lady were trying return a sound bar. I asked the sales clerk about the SD cards, he had no idea, and asked me to point that out on the flyer. After looking at the computer, and called someone else on phone. finally he said he has it in the warehouse, but one box already sold, there were only two available, he will have it here in a few minutes. So I waited for 10 minutes. I did not see anybody deliver the products, and he pulled the SD from a drawer. and asked how I would like to pay for it. I said Visa. he said he will have to charge me extra, and asked if I had a debit card. So I paid cash. He then said there will be no cash refund. I said it is OK as long as the SD were not defective. He said it is in a sealed package, it won't. By then, I just want to get out of the store as soon as possible. I already wasted 25 minutes in there. I had never brought anything from Visions before, this was a terrible shopping experience for me, I will not be back shopping there. Even if the SD are defective, I won't even want to return it. The sale person is by the Name George Chaplin.. On the receipt
