i think even if those 2nd bookstore accept them,they will only
buy in at very very low prices.
well personal experience told me so,quite a number of years ago,had
a few novels brought at 20+ each,wanted to sell them away (still
pretty good condition) so went to one of such 2nd handbook
store,quotation they gave me? They will only buy in books at 50
cents- 1 dollar each.I might as well just throw them away for those
prices they offer.
