I think I found the problem. I saved the drive to my buy later cart, and in my cart there was a 10% coupon. When I moved it to buy again, the drive showed up as 142. I moved the drive to the buy later again, removed to 10% coupon and when I transferred the drive to buy now, it comes up at 125.20. The 10% off coupon was overriding the 20% coupon. Try it.
