I have shopped with MF and I have had them say "How much would you want for this shop" on a least a few occasions. Of course that won't be all the time, but go ahead and ask, Nothing ventured, nothing gained. Ask for a high amount as a bargaining tactic, knowing that you would settle for less. Don't tell them what you would settle for. Also, I had an MF employee (name unknown), when I complained about how little they were offering in pay, said "Well, we (MF) have to make a profit too". Never mind the difference between what the client pays and what piddling sums they offer. MF is not a bad company however. They pay regularly, even if that money is low. Also, they pay directly into your existing bank account, not Paypal, if you so elect.
The bottom line is that you could always sign up for another MSC and see if they pay more generously. Good luck.
P.S. Paypal will issue you a debit card, which you can use at a typical store or restaurant. Also, you can "xfer" money into your bank account, although that will take a few days to register.
