All the acronyms and jargon got you confused? Here's a list to some of the ones I use most often
RP: Red Plum Sunday coupon inserts (ex. 4/17 RP = the Red Plum coupon insert from the 4/17 Sunday paper)
SS: Smart Source Sunday coupon inserts
PG: Proctor and Gamble Sunday coupon inserts
MQ: Manufacturer coupon
+UP: RiteAid +UP Reward
RR: Walgreen Register Reward
Here's a helpful link from Southern Savers with all the most common lingo you might find on couponing websites.
Also, I always list my price paid and total saved as the pre-tax amount, as tax rates will vary by county and state.
