Moving from Retail Arbitrage to Online is not particularly difficult, you will still encounter the same problems in prepping and shipping. The biggest issue you will face is item limits. While shopping at a local store, maybe you can get 20 of the same item, then you drive to the next store and get 30 of that item. It starts to add up with the quantity you can soon accumulate.
Online Arbitrage will have the problem with limits, but that should not stop you from being very profitable with this area. We have been very successful with ordering online and selling with the Online Arbitrage model. The problem we ran into, having 50+ boxes delivered at one time to our house. It’s different to get one or two boxes delivered, but when you take up half the UPS truck, that starts to be a challenge. Not only for you to received, but to prep and ship all that product back out.
Think of constantly placing your Online orders, shipping to our warehouse, we receive, inspect, pack and prep the items for you, then ship them back out. You haven’t even touched the item, yet you get the profit of that item in your account. This model for Amazon works, thousands will attest to that.
