No tests!!

I'm out of tests, I thought I had one more test for Christmas morning... now it's 10pm on Christmas eve and I can't find one damn test... and everyone is closed!!! I don't know where to get a test ? so much for that plan... I was gonna give a BFP to my SO as a stocking stuffer in the morning(if it was of course positive)
