i've seen several online retailers do this (not cigar retailers though). once you add to cart and start checkout, there is a timer which shows that you will lose the item after the allotted time. usually give you about 2-5 minutes.I don't think it's possible with the set-up of any online ordering system to have it work that way. Otherwise someone could put them in their cart, leave the computer for a week, and never complete the purchase. Then the retailer is stuck. A drastic example, but illustrates the point.
