3880 OEM chips needed for ILM carts

Hi, I need to acquire a full set of Epson OEM 3880 chips from almost empty Epson made cartridges. Unfortunately I know of no other 3880 owners, and CL has not offered a free/cheap printer lately. I did put the OEM chips I had into IJM carts with PiezoFLush to clean and prep the unit. Lastly please reply if you are someone who switches chips from ink carts to PF carts and the back again as a workflow. Thanks for the info!
