Sorry if this has already been discussed, I am no longer a regular here but ... Citgo"s special project" where you go into the store to buy items and get a credit card receipt, appears to have changed MSCs (while the "Trimark of Excellence" shops remain with the original MSC).
It looks like the new reimbursement is $1. In the old ones it was up to $6, but there was a $5 minimum purchase and it could be a pain hitting the "sweet spot" between $5 and $6, especially since Citgo tends to put their brand on run-down stations that often don't post prices on the merchandise.
Has anyone done them with the new MSC? Am I correct in assuming a single (low-price) purchase is OK now? And does the questionnaire vary significantly from when it was with the former MSC?
