If he's saying 14/4 then chances are he's either dropshipping from China, or not planning on posting for the 21 days until the funds are released. Is it an Australian seller? Click on their feedback number and it will tell you there whether they are registered in Australia or China. If it's China, then don't let them string you along. If it doesn't arrive, don't let them send you another one, just get a refund.
Without knowing the listing, chances are it is just a new seller that doesn't know what they are doing. However, these types of items are sometimes scam items set up by Chinese to rip unsuspecting buyers off. If they can string you along for the 21 days until their funds are released, they can withdraw the money and disappear. Generally they have lots of the same item at a cheap price to lure the unsuspecting. Often they are in a category that has no buyer protection, like the automotive categories.
Please come back and let us know how it ends up. Hopefully all will go well for you.
