For Marketforce, they tend to offer email bonus shops that but a 22 hour hold on the shop while the person offered the shop decides if they want to take it. They do a lot of those email offers in the last month of each quarter - trying to ensure that they get all shops done by their deadlines.
For Bestmark, that is odd. Usually there are at least 50 automotive shops but now there are none. I'm not sure how taking all of the shops off the job board helps them meet a deadline. I get it for Marketforce, but not Bestmark.
