I just purchased a new camera that requires a high speed sd card. I purchased the 64 GB Extreme Plus SDXC UHS-I Card. This card is on the SanDisk site and at Best Buy for $134.99. I think I found the same card at Target and Walmart for $39.99. Best Buy matched the price and I was out the door. Now I’m curious, was the Best Buy price and the SanDisk website price just an insanely high mark up or did the Best Buy employee make a mistake?
I’ve included the bestbuy website item, my purchase item and another store’s online price.
The only difference I see from the Best Buy website is that card doesn’t say V30, where the card I purchased does.
Are there any difference is the performance of t
he card I purchased? Is it really $134 or is $39.99 the correct or common price?
