Restricting High Value Item Sales

[random_code]

I want to restrict the sale of high value items to ebay profiles with a rating of 11 or higher.

On listings where this is the case I include a line that states this, yet people with a zero rating can still purchase such items. 

I cannot cancel citing the correct reason so what are my options?

EDIT: Thanks for the replies; it is as I suspected. Will remove these high value items and sell them privately due to the lack of seller support on ebay.

That is not an option on ebay 

You can restrict to bidders with non payment disputes and other things but not what you want to do.

Set your buyer requirements as tight as you can

You really need to sort out your listings 

("Please note that due to the high value of this item I will cancel purchases by ebay accounts with positive rating of less than 11".)

You can not do that and if you start cancelling sales because they do not fit your own policies then you will not be on ebay long
