amazon.co.uk wishlist with associate tag howto

I've found out how to link to your wishlist and include your associate tag in the url, so that in theory I get five percent of the purchase price as well. The URL is below
http://www.amazon.co.uk/exec/obidos/redirect?
tag=takeoneonion-21&path=wishlist/27OKOUOWR4Z4G
To unpack this, my tag is "takeoneonion-21" and to get the right code for the wishlist, the 270 etc after in the url above you need to logout of amazon.co.uk completely. When you do this, if you click on wishlist on the amazon.co.uk website you will be offered a choice of making one or searching for one. Search for yourself and copy the code similar to the above into the url string.
For those of you without associate accounts, don't worry about this.
