If the essays and information here have been helpful, we're glad to have helped.  Donations are by no means required (hence the term donation), but they are appreciated.  Clicking this button will take you to Paypal:

Guarantee: We have a simple, "If you aren't happy, we aren't happy" policy.  If you open a package and suddenly wonder why you bought it in the first place, you can return it for a full refund of your purchase price and the shipping one way.  Your only risk is the cost to ship it back to us. If it turns out that we made a mistake, then we pay the shipping both ways. I won't say "no questions asked" because we will ask so we'll know how to make fewer mistakes.

Payment terms:  We try not to be overly picky about the details.  If we can put it in the bank and pay some bills without any undo fuss, then we'll probably take it.  We're quite happy to take checks and money orders, and we're signed up with Paypal, which is the easiest route if you want to pay by credit card.  If you have some other method in mind, get in touch, and we'll see what we can work out.  Monopoly money, anything you may have printed in the basement, and chickens are right out.
