Quiznos deal $6 for two subs or two salads is even cheaper than BOGO

This is a really good deal at Quiznos — $6 for two subs or two salads, which is even cheaper than a Quiznos BOGO deal.  Have one for lunch, save the other for dinner.  Or, take a friend.  This is a Groupon online coupon deal, and not all Quiznos are accepting the coupons.  But I checked, and most NYC locations are accepting the Groupon coupon deal — including 304 West 34th Street, 16 East 23rd, 5-11 University Place, 84 Chambers nd 80 Broad Street in Manhattan; 2310 Jackson Avenue in Long Island City; Kings Plaza, University Place at LIU and 37 Hill Place in Brooklyn; and 8000 Utopia Parkway in Jamaica.
