I need someone who somehow knows his/her way around ebay.
Every day, I'll provide you with the Top 10 Best Sellers
with the exact keyword/keywords on all the ebays:
ebay.com, ebay.ca, ebay.co.uk, ebay.com.au,
(and also ebay.fr, and ebay.de, but not necessarily, hence, French and/or Danish a plus but not a requirement.)

What I want you to do is this:
1- First sell "it" (remember, we still don't have "it") on the site that goes for the highest price (most expensive) and, then:
2- Buy "it" from the site which sells "it" for the lowest price.

For example, I'll tell you that "canon ef 70-200mm" sells for $800 on ebay.com.au and sells for $1000 on ebay.co.uk (and on ebay.fr for $1200 ; that's why
knowing French and for ebay.de, knowing Danish helps a lot!!!)
Another example: "iphone 3g 16gb" sells for $170 on ebay.co.uk and $450 on
ebay.com.au.

For more clarification, please contact me. Thanks.
