Late to the party, here. Thank you to Daniel Price. Is the increased pay just for the one poster, or is it for others? tia.
The only real universal concern: potential monetary cost to the worker. Are you driving a great distance? Are you purchasing a significant number/expensive amount of stuff? (I have an unlimited card and would not wish to push this issue, but I could if necessary.) Do these gigs fill in a larger schedule for you, or are they stand-alone or just a few for you?
Just for me: Easy peasy! In the first round, only one location had the designated product/specific size. All units were acceptable. In the second round, several locations had the designated product/size. All units were acceptable, and there was nothing to buy.
YMMV.
