Pay on pick up

A buyer won a bid on my bulky product that was for pick-up only coz of its size, After 2 days without payment I sent buyer a soft reminder about payment and collection of the product.

3rd day, buyer emailed saying they have no paypal account and will pay upon pick up.

I checked buyer's account and was opened 06/2014.

Any words of caution in cases like this? 

Thank you very much.
