There appears to be a major flaw with the bulk edit facility currently. Earlier this evening I used bulk edit to change shop categories on fifty listings and it removed all postage information – price, postage method etc.
This left buyers with the ability to purchase items without paying postage. For a seller that doesn’t realise this could be financially disasterous, especially on heavy items where postage is high in proportion to the sale price.
If you use bulk edit beware, it’s probably in your interest to use the edit and synchronise live listings in TurboLister in preference to on eBay as this appears reliable. (And in fact is the method I used to restore postage method and cost to all my listings).
