Score a nice deal on Old El Paso taco shells at Target! Yesterday I posted about how to score Ragu pasta sauce for as little as $0.53. Old El Paso taco shells are part of the same gift card promotion: buy 10 and receive a $5.00 Target gift card. Match the promotion with a printable coupon to score ten boxes of Old El Paso taco shells for only $0.40 each! The coupon requires Java to print, so if you’re a Mac user I recommend printing in Firefox. This is a long-term promotion, so if your store is out of stock, hold on to the coupon. Mine printed with a 30-day expiration date.
