Yes, I'm selling a HP 15c on eBay under my nick name Datamath-Calculator-Museum.
No, it is NOT for the profit.
Please let me share some facts with you:
The Datamath Calculator Museum is not for profit, it is a hobby. But it is not a cheap hobby, every collector knows that the last 10 items you are looking for are pretty expensive.
I decided long time ago to avoid any Google Ads or similar advertisements on my website and to make all scanned and PDF'd manuals available for free download.
I'm on eBay since 1999 and changed my ID in 2007 to built up a good reputation in selling calculators to COLLECTORS (not bargain hunters). In the past 12 years of buying calculators on eBay, I received a lot of crap. I could easily sell dozens of boxes of 25 trash calculators, each.
Each USED calculator I sell is tested and cleaned twice: The day I receive it and when I take the pictures for the auction. I describe every flaw I notice and take crisp pictures of each calculator. I accept returns and the rate is far less than 1%. The last one was an ADLER with a non-working [4] key. No idea how I could miss this...
I received from other "Pro" calculator sellers multiple requests in the past two years:
1) Sell only for a (high) BUY-IT-NOW price
2) Let's agree on minimum prices for some "rare" calculators
I still sell my calculators auction style - but changed recently the minimum price from $9 to $19. I had a lot of calculators ending up at $9.50 or so averaging my "profit" (w/o eBay fees!) around an hourly rate LESS than MINIMUM WAGE in Upstate NY!
I received a lot of emails from buyers, too:
3) Can you make a BUY-IT-NOW for this calculator?
Answer is always the same: NO - and a few names are already blocked from my auctions for this reason.
And the HP 15c you might ask now?
Four of my international collector friends asked me for some assistance in purchasing HP 12c and 15c's and SHIP them.
I simply purchased two each, more - expecting some change for my next great purchase of either the Exactra 100 prototype (asking price is two grands!!!) or a TI-88 in the transparent housing (no asking price so far).
Thanks for your time reading through this message.
Best regards,
Joerg
