Totally scam about their service. Wish I can put negative 5 star here.It appears to be a pay-per-use service but there is a 15.99 monthly charge hiding.
They won't send you any bill for that charge--and wish you forget about it. I realized that several months after they charge me for more than $80--and I can't print a postage from their website--you need to install their App--that could be bad for your security, since this company is so shameless. You can get everything from usps.com without any monthly charge.
BBB investigated this company last year, FYI.
The stamps.com promised to improve transparency--but no, they didn't, yet. Stay away before the problem is resolved.
