I shop often at Walmart, and their POS system is fairly easy to use for partial cards. I'm not positive, but I think they can use the Meta cards for MO's for a swipe up to $99, and so if I had low-balance cards I could possibly swipe 4 of them to get a MO. (I'm not sure because I haven't bought MO's in quite a while.)

I'd still prefer though to not have to cycle prepaid cards through my wallet if possible. Aside from my health insurance premiums, my largest annual spend category is airfare.

None of this is directly relevant until the fall when I end Obamacare and go on Medicare; I'm just trying to get ahead of the curve.
