Ebay

You buy a Tronxy, you buy a headache... this one is still a relatively new printer, so how much of a headache is yet to be seen, but expect a headache. ...

They got a bunch of BOGO items listed on their page. Some are not bad... Price after code FRESHFIND20 at checkout.

No bulk/bundles discounts... these prices are per single roll. Refills are $8.79, regular rolls are $9.59. Good color selection for PLA. Check this ...

About 1200 or so listings, which is not bad. Poke around... Feel free to use the Ebay Deals page i setup to help get through everything quickly :)
