The nearest published preset, Micro at 1 / 2 / 20, is USD 5.11 and therefore over the line. 15 GiB of disk instead of 10 would be USD 4.93. Its credit is non-refundable in cash and its disk is deleted seven days after the balance hits zero, so it is a prepaid bet rather than a subscription. The domain is seven months old.
