I use Ali express for drop shipping so I was curious when I saw Modalyst because I would like to use drop shippers with better shipping times (Ali express is 2 - 6 weeks on average). I really don't understand the point of this service because (1) The retailer margins are terrible (2) The Shipping is just as slow as Ali express and (3) The product selection is seriously lacking (aka need more suppliers).
I'm not sure what the point is but it seems to be working for some people.
