Of course, if that happens, they'll have to delete the wording on their website that states they don't charge their authors a penny.
PA: We don't charge authors a penny!
Author: What's this $10 fee, then?
PA: That isn't
a penny, that's 1,000 pennies!
Restocking? They're going to toss those books into a Dumpster in Frederick.
Author buys 30 books at $24.95, 50% discount. PA's income: $374.25 PA's cost: $90
Shipping costs are paid by author, and may be a profit center to PA, since shipping actually costs less than they charge. But let's just say (to keep the example simple), that their shipping charges are honest (Ha!). Cost to PA: $0
So far, PA has a profit of $284.25.
Time passes. Author manages to sell 10 copies, and returns 20. Author pays shipping; cost to PA, $0. PA refunds $249.50 but charges "restocking fee" of $49.90. Profit to PA $84.65, but note that they get to keep the entire $284.25 in their bank account, earning interest for them, for up to six months (assuming that their record keeping is up to tracking the payments owed to the authors, and assuming that they don't decide to end the "experiment" in August, two weeks before royalties are figured, so Sorry, Charlie, No Refunds After All).
The returned books get send to the Frederick Landfill (if anyone orders a copy of that title later on, they'll just print up a new one and charge full price).
In effect, PA has sold 10 books that they wouldn't otherwise have sold, and gotten a substantial chunk of change to earn interest (or cover the February royalties--we've gotten used to PA pulling some bizarre fund-raising scheme just before royalties are supposed to be posted).
PA is betting that few of their authors will be able to part with their "babies," anyway.
