I can also liquidate them free with BB (except for AGCs. Can they be liquidated with Serve?). My problem with low denomination cards isn't unloading fees. I find it a pain to buy 150-300 low denomination GCs each month. I find it a hassle to keep track of several hundred GCs per month. I'd rather pay a bit more higher denomination options.

The big draw of Serve would be to load directly with CC at no charge. Even this is a relatively small play. Two Serve accounts would only generate $220 / month via direct CC loads. I think the highest CB card right now is 2.2%. Serve is very efficient, yet would only be one component of MS.

Also, I have two BB accounts and don't have any more friends or relatives that I can recruit for more accounts - I eased MS into a conversation and they recoiled. So, I am limited to two BB/Serve accounts. I am leery of shutting down my BB accounts to open Serve accounts. It takes over a month to do this. BB has been rock stable for a long time. I'm not sure the no fee CC credit card loads at CVS will last long term.
