I've been selling on eBay since February 1999. Although I have bought several items, most notably my Summa D60, I am a seller. I've sold everything from Winter Olympic pins, Fossil Watch tins, Victoria Secret bikinis, Harley gas tanks, Sunbeam popcorn poppers all the way up to a $9,000 Hobie 21 catamaran sailboat and many other items. I have had only a few problem buyers in all that time. As a seller, I've never lost money. As a seller, you have to honest, clear, descriptive and rapid communication is essential. I have a feedback rating of 1101 and it's 100% positive.
My eBay name is rycpirate.
I have looked into selling RTA vinyl which I am very interested in. I am not ready to start yet, but will be under the Decal_Designs name when I do. My interest is not in doing Calvins and the like, but rather in designs I make myself using the raster to vector method of producing cut decals. I have so much to learn still, but enjoy it very much. Right now I'm starting over and reading every single help page of Vinyl Master Pro.
I'm very familiar with eBay and it's positives and negatives. After doing some research on a few other choice RTA sellers on eBay which I keep track of, and analyzing their feedback ratings, multiplying their lowest priced sales by the % of feedbacks left which is only about 60% of all sales, figuring in eBay fees and materials cost and the small profit made on shipping and handling for each sale and many of these sellers are pulling in well over $30,000 a year net just on eBay RTA. It's a lot of work, but it is profitable. These sellers that I keep track of are mostly selling things other than Calvins and No Fear type stuff.
This is a major portion of what I want to do, but not limited to it.
When looking at vinyl signage in general on eBay, it gets tougher to make a good profit on banners and coroplast etc. However, it must not be overlooked as a source of sales and contacts for future signage. The tricky part is coming up with something unique for eBay at the right price and still make a profit. For eBay, profit has a lot to do with volume and also up-selling and cross-selling your new contacts using flyers, price lists, websites etc. There are many ways to automate much of this volume as a seller so it's not as overwhelming a task.
If you make something you think is fairly unique, sell that. That is what ebay buyers will pay more for.
Also, it is wise to separate your volume RTA sales from your other eBay sales. Selling anything in volume is bound to get some negative feedback. It is harder to satisfy every last person with RTA stuff.
