3 ms·They have a code after /dp/ - what is that for? Looks like an affiliate code to me. Edit: doh!by quickthrower2 8y agoThey have a code after /dp/ - what is that for? Looks like an affiliate code to me. Edit: doh!greeneggs 8y agoNot an affiliate code. After the "dp" (detail product) is Amazon's product code. You can delete the rest of the URL except for dp/thecode and it will still go to the same product page.joegahona 8y agoIt's not. Search the same product on Google and the URL will be the same.
