hi  i can see that you have put on some of your items  a warning about handling times  thats good.

but you can see what the buyers see , now i clicked on 1 of your items and it says estimate delivery up to the 4th which is 6 days away , which is fine , but then have another look and its the 4th of december  36 days away. but some buyers might not have seen that , and that might be the reason the buyer is now not happy jan. mind you looks like you have only had 1 not happy buyer , so count yourself lucky. unless you sell hard to get items , i am sure buyers would go to other sellers to buy from , without an aprox month handling time.

even though you prob can get the feedback deleted  because of your handling time. but because you have some cheaper items that prob dont have tracking , you might get some nasty buyers saying they did not get there item  or its not as discribed or whatever.

thats my opinion, way too much handling time.
