There have been many posts on the topic, so I will go through it breifly.
There are a few users who are spoiling sales of seller:
Whenever they see a hot selling product, they simply purchase the entire quantity (without intention of paying for even one quanity), thereby closing the auction.
Seller support says there is nothing which can be done.
Earlier, sellers could decide on the maximum quantity a user could purchase. We humbly reqest that this condition be brought back again. When this policy was changed, we protested via a posting in this cafe but no action was taken.
If this is not feasible, than as Sanjay Verma has said in an earlier posting that buyer limits would be enforced. Please have a limit for that any user cannot purchase more than 5 qty. of any product. We beliver no user actually purchases more than 2-3 quantity of a product. We say this after being on the site for more than 2 years and have transacted 15,000 orders.
Please act urgently on this matter as this is causing a lot of frustration to all sellers.
