I absolutely agree with the OP that it is wise to find other ways of selling merchandise other than eBay and Amazon. eBay and Amazon are fine for the casual seller working part-time, but those of us who depend on sales for our livelihood know all to well how easy it is to lose an account.
Spend a week in the hospital. When you come home, you may find your account gone. Even if it is still open, the low DSR's that you will receive might still kill it.
Having your own website is the best way to go, IMHO. At first it can be discouraging. You put in a lot of time and effort and then see very little in terms of traffic and sales. But it is a building process that works over time. If your mentality is that you must have 2,000 sales in the first month, you will surely be disappointed and give up.
SEO placement is BRUTALLY competitive and the big players can afford to have whole teams of people working on their campaigns. And often, a beginner has no idea where to start, let alone the money to compete. Ditto for pay-per-click advertising.
But we have ONE BIG ASSET that very few of us take advantage of. We have eBay and Amazon sales. That means CUSTOMER INFORMATION. My website is not linked to ANY of my stealth accounts in any way. Every time I make a sale, I wait for about 2-3 weeks and then send a postcard (large format, professionally printed) with a coupon good for $5 off on a first purchase. I also offer a free gift to each new customer. 3 months later, I follow it up with another one, if the person has not created an account. Maybe 5% of my customers sign up. But since there are no eBay/PayPal fees to pay, it is profitable for me. And the repeat business and word-of-mouth business is something that money cannot buy.
For this to work, you must EXCEL at customer service and FAST shipping. That means a daily trip to the post office, maybe two. These are the two key ingredients that bring people back and also bring in new business. I have been doing this for two years and I have about $5k in monthly sales from my website. If, however, you get easily discouraged and give up after the first couple of months, this will not work for you.
Amazon did not magically appear one day with $15,000,000,000 in sales. For years, they burned through investor money, using affiliates to acquire customers. In the early days, investors preferred eBay as the return was more immediate. Amazon investors were wondering WHEN, OH WHEN is Amazon going to show a profit? But now, they beat eBay. However, this was MANY YEARS in the making. Success happens over time. I remember Ellen DeGeneres once said that it only took her ten years to become an "overnight sensation". Translation? There is no free lunch.
Success takes time and effort. It also takes a long-term approach. If you start today, you probably won't be minting money tomorrow. I look at every eBay, Amazon, Ioffer, Half, or whatever sale as an opportunity to turn their customer into MY customer. Offer them a great deal and ship fast. Offer them a discount when they refer someone. Always be professional and polite. Give refunds when necessary. Nobody likes refunds, but they are a part of doing business.
Seek out other venues and new methods of reaching people. But don't think that you need the latest and greatest fad to be successful. You can do just fine WITHOUT Facebook, the mobile web, or whatever. But if you are lacking in customer service, or if you are lazy and just want to go to the post office once a week, you can forget about ever being successful.
Don't fall for sales pitches that promise to get you to the top of Google in 7 days for a few hundred dollars. They might actually work for a few days, but you can get blocked by Google for breaking their rules. Slow and steady wins the race. There is no quick and easy road to riches. Following those paths will only lead to disappointment and frustration. Nobody is going to share a TRUE formula for success with you for $19.95 or even $1,999.95. You have to make your own path.
