Have to get the best deal

What would this ocd be? I feel like I have to always get the best deal and it drives me nuts. I’ll price check with multiple stores, and then go to multiple websites to look for promo codes. I also have a fear of getting ripped off or having a bogus credit card charge, so I take pictures of all my receipts just in case I see something on my credit card that I don’t remember. I hate it. And recently, on one receipt my thumb is covering the stores name so it really bothers me, even though the stores phone number is still on it so it’s obviously them and I remember going to that store and the receipt has the exact price and date as what’s on the statement. But my ocd is making me “prove” to myself over and over again that the receipt is from that store. I need to do erp on this, but I don’t know what I’d do.
