Got a starter pack of Epson photos paper with printer. More than pleased with the results. However, when i am looking for paper packs it all adds up to more than sending them off to print.

1. Ultimately is this the best thing to do (after all, i don't know the final end result)
2. If not, where can i bring the cost down.

Happy to buy in suitable bulk.

Any ideas/links greatly appreciated.


PS using a PX650 (if that matters)
