Yes, it is a viable business but you have to go to where the customers are, forget bricks and mortar, your own website unless you have a big marketing budget. You have to sell through sites such as Amazon and eBay who do all the marketing for you. Yes, they take a commission but it is a lot less than you would spend trying to promote a business yourself. You can also start it up while still having a full time job, all you need is a mobile phone or tablet Selling anything online has its drawbacks, there is an ever increasing problem of fraud and abuse by buyers and the basic rule is don’t sell anything you cannot afford to lose, both it and the money. It is not as big a problem in the world of model railways as its it getting elsewhere but basically if you have a dispute with a buyer you are going to lose. EBay, PayPal have seller protection but it’s not worth a dime. As the seller, you cannot prove you sent them the item you claim to have; you can’t prove they did not send you back the item they said they did. Any disagreement and places like eBay will come down on the side of the buyer, they guarantee the buyer the item they pay for and that means if a buyer is prepared to lie through their teeth then there is absolutely nothing you can do about it, kiss the item and the money goodbye. Even if hell did freeze over and eBay did come down on the side of the seller then they can just appeal to PayPal. PayPal can ignore any judgement made by eBay and then even after that if funded by a credit card they can appeal to the credit card company. In all these cases it is up to you to prove what you are saying is right not the buyer. A chargeback on a credit card can occur up to one and a half years after the transaction and it’s up to you to prove the chargeback claim is false. Larger retailers just look at it as a cost of business, online buyer fraud instead of older forms of stealing such as shoplifting. Most people do not care, as they are only ever buyers. For a small business, it can be a big problem even if it’s not fraud the ability for buyers to return delicate items such as locos after having them for nearly a month often means they arrive back in a state where they have to be heavily discounted. In other market sectors such as clothing it’s a standing joke, buy the clothes, don’t take the labels off, wear them for a couple of days and then return them. Free clothes for life and you never have to wash a thing. It amazes me there are any small retailers left
