If you sell or buy on eBay, then you should be checking out the new tools available at Mavin. They offer tools for pros and noobs.

Greatest site ever. I am impressed. Perfect source for sold prices. Well done. After using it for the past few weeks I love it. It's a simple interface and it delivers the info you are looking for easily.

Additional Details

When will I be charged?

You'll be charged if you selected a paid plan, and then every month therafter until you cancel. You can cancel at any time.

What if I want to cancel?

We'd be sad to see you go! But we do make it easy to cancel your account. You can click the "Cancel my account" link on the My Account page at any time to cancel your account. Once cancelled, we will stop charging your credit card. Your account will be active until the end of your billing cycle, at which time your login will continue to work but you won't be able to save items or view your collections.

Is there a limit to the number of collections I can create?

No. You can create as many collections as you like. You're only limited by the number of items in your plan. If you hit your limit, we'll give you the option to upgrade to a bigger plan. We give you the choice, you're in control.

If you have questions we didn't cover, we'd be happy to answer them.
