Price adjustment needed

Hello,
I made two motherboard/cpu bundle purchases on November 17, 2020. Both were priced the same for the bundle. I made a pickup reservation for them both, each bundle priced at $569.98 (not including tax). Earlier this month I examined the receipt, which is still under the refund/return policy period, and noticed that one of the bundles was charged $100 more. I even have screenshots of the cost of each bundle before purchasing them. This feels like a bait/switch in price. Someone please contact me to refund the price difference! Thank you.
