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.

Not possible & potentially damaging to sales as a buyer with 4 positives may be a brilliant buyer....while one with 11+ could be the buyer from hell as buyers can only ever receive positive feedback

Much better to simply tighten the blocks available to you
