The downside to buying these papers are: not every store carries them, they are a bit more expensive, and they do not contain our local store ads so if you want to look at the ads you will still need to get a GBPG.
Coupons are regional and larger markets get better coupons. Even if you buy these big city papers you may occasionally come across a coupon that you didn't get. That's because I use a national database to search for coupons and I have no way of knowing which coupons were in which paper. Believe it or not, I don't even buy a Sunday paper! I get multiple coupon inserts and ads from family members who don't use them. So sometimes I type up my deal lists before I even see what coupons we got!
A couple years ago, one of our GB Savers (Vivian) did a coupon count and this is what she found:
A Smart Source in the GBPG vs. the Milwaukee Journal Sentinel had:
Food coupons 8 vs. 14
Household/toiletry coupons 7 vs. 24
Medication/vitamin coupons 2 vs. 10
Total coupons: CT = 196 and GBPG = 79
Food - 78 vs. 36
Toiletry - 43 vs. 16
Pharmacy/Meds - 22 vs. 6
MakeUp/Beauty -16 vs. 5
Cleaning - 17 vs. 7
Pet - 11 vs. 0
