Hi,
I used Jasvy as my printer recently. The only thing about Jasvy is that you need to check the proof very carefully because there are quite a few mistakes. But, i was ok with that because we had to check and approve the proof anyway.
The thing that i like about Jasvy is that they are able to give you the proof and complete the printing very quickly. Once you are able to confirm with them and your wordings on your card, they are usually able to give you your proof within a few days.
Then, depending on how long you take to review and approve the proofs, it takes about 1 week for the cards to be ready.
So, by the time i got my printed cards, i had plenty of time to start writing them.
There is a lady there....Ivy, very friendly and helpful.
