Purchase Arduino ?

FastCat try contacting a vendor directly. They might be able to accommodate your needs.

But take a look at paypalsucks.com. If someone is unwilling to use paypal, I think we should respect that choice.

That site is mostly FUD just so you know.
Paypal did have a rocky period in its history (when that site was started) but eBay bought it and cleaned it up.
While there is occasional problems, most people use it just fine.
