There are many sellers offering virtually new Dell laptops which have been returned unused for various reasons. This seems to happen only with Dell, probably because they only sell by mail order or online.
I have seen several instances, however, in which these laptops have sold on Ebay for more than the original Dell price! For goodness sake use your head and check the Dell website first!
It's just happened again. Someone has paid £510.00 plus £24.99 delivery for a RETURNED Dell Vostro 1400 when they could have had a brand new one of identical spec direct from Dell for £504.08 including delivery. Unbelievable!
