I'm taking a few grad courses and need a Texas Instruments TI-83 Plus.
They go for $40-100 depending on condition, but if someone has 1 they'd like to sell, please let me know for Bitcoin.
Send me a PM with your offer and your bitcoin address and I will pay it right away!
I would like to have it by Thursday and willing to pay extra for 2 day shipping.
I've bought/sold from a few on this forum, and recommendations available
EDIT: Thanks for everyone who emailed offers, the sale is over
