don't want to get anyone's hopes up too high, but while UPS Saturday delivery with a Monday scheduled date is improbable, it's absolutely possible.
when Nike launches a "hot" shoe, many times it's on a Thursday. I've had multiple times this year now when I place an order on Thursday, the shoes ship out Thursday night with a UPS scheduled delivery for the following Monday, and all of a sudden the package ends up at my doorstep Saturday around noon.
take that with a grain of salt obviously, but I'll be hoping this is the case here haha. like I said, this has happened to me with Nike/UPS at least 5 times this year. if not, 24th vs 28th is already a great improvement and I'll take it.
