I'm looking for a place to buy very small amounts PAYG - preferably no limitations or very long limitations on how long you have to use the transfer and no monthly. Very small setup fee or no setup fee.
Origin pull, a couple CNAMEs, only need US-WestEU/don't need apac or ME.
I really doubt it'll use more than 1-2GB or so every several months.
Out of curiosity, how does billing at low prices work in general? Do you typically deposit money (I used to use simplecdn - deposited $5 once for probably a year or two without any further bother, after they went down I just had everything served normally, without cdn) or are you sent a bill at the end of the cycle or when costs hit a certain amount? Hitting a card for $0.50 probably would be rather pointless
