At the CVS scanner/coupon printer I got a Boost coupon Buy two Get one free.
Boost high-protein was giving $2 ECB for each 6pk purchased. I still had some
peelies "Save $1.50 now", which can still be found in some stores.

The B2GO actually returns $9.99 instead of the cost of a 6pk.
3 peelies can be used even though one is free
3 $2 ECBs print even though one is free

2 High Protein Boost 6 pk 2(8.49) = 16.98
Third six pack ($8.49-9.99) - 1.50
3 ($1.50 peelies) - 4.50

Cash 10.98
3 ($2 ECB per 6 pack) 6.00
Net Cost for 3 6pk 4.98

Big YMMV on getting the B2G1 coupon at the printer, and finding the peelies.
