Umm well i kinda new to this stuff and english not my first language, could u explain me what means Back Order? and why it takes more time to complete?
Back order means the vendor is sold out, but expects more stock from the manufacturer. Back orders are usually first come, first serve. In other words, the newly received stock will ship to customers in the same order as purchased. A good vendor will list the estimated time required for a back order, otherwise you could be waiting indefinitely (within legal limits) for your order to be fulfilled.
As far as I know, such limits in the United States would vary by state according to each state's consumer protection laws. In my opinion, if a vendor can not provide an estimated backorder delay, I would suggest shopping elsewhere. Many vendors also allow you to cancel a backorder at any time while waiting, but you need to closely read the vendor's specific purchase policies to be sure.

There is an FTC rule that puts down a 30-day limit to ship. Anything beyond that must be agreed upon between merchant and buyer.
