I've heard lots of people say they don't understand the jargon used on many of the couponer blogs, so I thought I'd address this problem. Here is a guide that should help you wade through the various blogs and their lingo.
Types of Coupons:
IP=Internet Printable Coupons
RR=Walgreens Register Rewards (these print out after your order is complete, and they can be used on your next purchase)
IVC=Walgreens Instant Value Coupon (found in the monthly Easy Saver Catalog)
SCR=Single Check Rebate (at the end of the month all of your rebates from Rite Aid will be mailed in a single check)
Catalina=Albertsons or Safeway coupons that print out at the end of your order and can be used on your next purchase
Double Coupons=Safeway, Thriftway and sometimes Albertsons have in-store double coupons that allow you to double up to 4 manufacturer coupons at up to $.50 each, for a total of $2.00
SS=Smart Source Insert (found in your Sunday paper)
RP=Red Plum Insert (found in your Sunday paper)
P&G=Proctor & Gamble (found in your Sunday paper)
Leave me a comment if there's other lingo that I haven't addressed here and I'll add it.
