7 Ways to Save on TI-84 Graphing Calculators

If you just noticed that your child has to get a TI-83 or TI-84 calculator as part of their school supplies – you might also have just seen the sticker price.  Ugh.  At around $100, this is definitely time to go deal hunting!  Here are 7 ways to save on the Texas Instruments TI-83 or TI-84 Calculator:


For the easy deal, take advantage of Amazon & Walmart’s ongoing price-war with each other.  They’re just constantly trying to best each other and it benefits us!

Yardsale Facebook Pages:

Search Facebook for a yardsale group near you – and say that you’re ISO a graphing calculator (In search of).  Scroll down to see my tips for buying on these sites.

Local College Facebook Page:

Are you living in a college town?  Search Facebook for a yardsale or resale group specifically focused on the college kids.  Besides being a likely place to find a calculator, you might also be able to score some cheap furniture as the old group moves out of their dorms ;)

Used Book/Music Store:

There’s a nice book/music store near us called McKay’s that is buying/selling graphing calculators this year.  I haven’t been down there yet to see how much they’re running – but anything will be a good deal if it’s under $80.  If you have books, cds, video games, etc… to sell – you could get trade in credit for an even better deal!

Put the word out:

Ask friends, family, church members, etc… if they know of anyone who has a TI-84 for sale.  Chances are, someone has one in the bottom of their junk drawer and will never use it again.  Heck, they may even give it to you for free!

Craigslist: I found TI-83′s, 84′s and 85′s for as low as $35 nearby – this is a great option!

Ebay: I found TI-83′s from $35 – $60 that were certified in good condition.  Also a great option!

Ask around at school or your own adult friends to see if they still have theirs and would be willing to give it up.  You may wind up with a free one!


A Few Tips for buying from an online seller (aka – Facebook group)

  • I got my son’s calculator this way – and while it went fine, it was a bit of a drive.  You should always choose a SAFE PUBLIC MEETING PLACE – and preferrably one that’s halfway between you both.
  • Don’t go to the person’s house – there are too many horror stories!
  • If someone replies to your “searching for a calculator post” – continue to hash out details over facebook messenger, rather than putting all your business out there for everyone to see.

    Also good idea to check at pawn shops. I bought my 2 kids both a calculater each at a local pawn shop – gave $10 for one and $12 for the other.
