I would wait a few more days since it is a holiday weekend. It¹s always best to err on the side of ³benefit of the doubt². If that doesn¹t work, open an unpaid item dispute for the auction. This will send a unpaid item reminder to the seller and will also document the process so if for any reason they don¹t pay, you have recourse for a fee refund.
Also, keep in mind, that if it is a big store, they may be backlogged due t o the holidays. They also may take some time to process orders and purchases. While this is not acceptable, sometimes it¹s the reality.
Good luck.
