Why are doubling cubes so expensive?

[jesjosacosta]

There is nothing that differentiates a doubling cube from any other normal die except the numbers, and perhaps size. So why on earth are they so expensive? On average on ebay, they run $3.75 with a $1.87 shipping fee. Its one die!!!! I should be able to buy these for something near a quarter, not $5.00!!!

http://www.jspassnthrus.com/backgammondoublingcubes.html for example has doubling cubes for $2.80 and $4.60 not including shipping.

Does anyone know where I can get a few doubling cubes for a decent price?

Here's one for 75 cents.
It's black but it's proud, say it LOUD!

That's outrageous for sure, but it looks like you found some on ebay anyway 

What about home made ones ?  They hardly need to be precision now, do they ?

I mostly rent doubling cubes, cause most of them come back to me in any case.
