try hang ga street. we had 200 double sided cards printed on GOOD quality stock for 140000 dong. they designed them on the spot and were ready in 48 hours. if you do a better price good on ya!
every shop here seems to print business cards and wedding cards.( almost a good enough reason to get re-married - to the original person off course!)
we went to 91 hang ga and there was someone who spoke reasonable english.
if you have a usb you may get a better price.

Single sided, two color logo. Costs us 65k/box of 100 cards.

They'll print your design and logos, but most shops will redo the whole thing in AutoCAD. The shops love their AutoCAD for some reason.

Triple check all proofs before printing, because good enough is usually the M.O. for these vendors.

Thanks for the replies. Got 100 cards, single sided, two color for 40k in a little shop located in 89 Hang Ga. However, no English speaking people there.
