it varies between sellers, some seller can take up to 2 weeks, but these types of seller almost always state this in the item desscription. if it didnt mention the time from purcahse date until ship date, I’d expect 1-2 days at most.

There is no set time that I am aware of but a good seller will note his shipping schedule in the listings. Some will ship within one to two days of payment. Others will note they only ship once a week and mention the day. Good sellers will also email you when they ship the item. If all else fails, just use the “Ask the seller a Question’ link in the upper right hand side of the listing page and ask the seller when the item was mailed or will be mailed.
