Sorry no refunds.  Would be a great stance for them to take.  Canadian Tire does this on Christmas decorations with no returns or exchanges after December 18th.

Walmart made it 30 days for the PS5 store refund. After that, get fucked or exchange it for some eggs.

That first wave was lucky for these scalpers to sell it for double, it's over now.

Highly regarded.
