Hey there, Is it legal to make you're own affiliate store? Like selling WoW Game cards and buying them directly from another website? So when a user clicks buy i get a message, i go buy them somewhere else and send it to this person?
If you are buying and then selling them on how are you an affiliate? Are you intending to do this without informing the company you are buying them from your intention to resell or are you being open with them? You would need to read their T&Cs on the matter if your not. The other aspect to consider, what do you do if this company decides to decline your orders?
It is not illegal but may be a breach of contract with the vendor you are buying from. The bigger concern is that if the people you are buying from "spot" what you are doing and refuse a sale then you will have to find another supplier for the item. With your model you will also not be able to give stock status nor any estimate on delivery. If you are wanting to avoid holding stock you may want to look into dropshipping arrangements instead. It could also be worth approaching the company in question too, if you are bulk buying you should be able to get a reasonable discount. If they can post direct to your buyer they will also accelerate your distribution.
I don't understand why you are an affiliate if you buy the product. It should be a dropshipping or ecommerce where you fulfill the product yourself or by your dropshipper.
