Prices by computer for envelopes:
$20 setup fee which is doing whatever is needed to get your information into whatever font you want. Usually this is with a word doc list. If I have to retype each one it adds $0.15 per each to the printing price and a $20 setup fee.
Printing is $.65 per envelope
Adding the return address on the front is included, on the back is an additional $.25 per envelope.
Printing return addresses on RSVP envelopes is $. 25 per envelope.
I require at least 10 extra envelopes to allow for mistakes.
