Mod daz stated earlier in this thread that repost is allowed if the sale changes
Also not being able to sell a ls quickly usually means you have to high price so just go down in price and repost (wich as stated is allowed if the post change content) If you are on premium it doesnt really matter for you if you sell or not. And if you want to complete a time achivement then just give the ls away just to make sure (it happens that i give ls for free when i dont want to wait)If your request has changed within the allotted time, then posting a new request is allowed. For example, if you were selling two or more lootspots and one sells, you can advertise again to sell the remaining lootspot.
