To help pay for website costs, or simply say thanks if you found my stuff useful, you can ...

If it doesn't work, or if you prefer to use something else than PayPal/cards, email me and tell me an alternate payment method. (I only have PayPal so I haven't really looked at alternatives yet.)
To send something nice in a letter to me, here's my home address:
Henrik Erlandsson
Dukers väg 105 C
57536 Eksjö

Thanks! :)
