First, what is a webkinz, I know may people don’t know this and have just been given the task of finding a Webkinz that isn’t sold in stores any longer. According to the website:

Webkinz pets are lovable plush pets that each come with a unique Secret Code that lets you enter Webkinz World and play with a virtual version of your pet.

Now, were do we find them if we can’t find them in the store any longer? The Internet! I would start a web search, remember ebay isn’t the only place to find used or pre-bought items on the net. Go to www.google.com and type in +buy +webkinz , adding the plus sign before each will make sure both words are in your search. With the search you should be able to find at least 3-4 places that are selling the Webkins animal you’ve been wanting. Now use these sites and ebay to compare prices and always remember shipping! one of the biggest ebay scams is to add 3-4 dollars to shipping than is needed, it’s just more profit in their hands. If possible I will always try to find a seller that has the shipping form from the post office on their site, this will show the true shipping cost. I should cost no more than 3.00 to ship a webkinz! Being a stuffed doll, they are very light.
Unless you’re looking for a rare webkinz than you should have to pay more than 20.00 for one, people are buying then off the net and at wholesalers for 10-14.00 and then turning around and selling then on ebay for 30.00 plus 10.00 shipping.. Do Not Fall For This! that is unless you really have to have it and don’t care what you’re paying.
Just remember use other sites to compare prices, is it new, has the code been used? these are all good questions to ask yourself and the seller if you’re thinking of buying off ebay. Other than that, happy ebaying !
