Just browsed ebay a little today. I have not looked for quite some time. I am stun that there are almost 5000 listings for HP refill kits right now on ebay. A quick browse I found something really interesting that quite a few vendors apparently deliberately flood with items listed repeatedly in large numbers every few hours. A refill kit sells for $0.99 with 2 - 3 dollars of shipping can be listed hundreds of times in a few days. I can't believe this. Do they think people will believe that such products are actually usable? I have no doubt those are cheap Chinese imports. Wow! it is so easy to identify those. Just see how many times they repeated the same item each day. Believe it or not they do get a few buyers. Maybe quite a few buyers. It is totally entertaining to see how they sweep the flea bay and ship US dollars in the returning cargo containers back to China this way.
