If you have a standard account you don't pay any PayPal fees to send or receive money.
You are limited each month on your amount if you don't have a biz account on Paypal. If you don't intend to sell much, standard may work for you..however I don't buy from anyone who doesn't accept my cc, since that is my ace in the hole if you misrepresent your item. My cc will put a hold on the Paypal amount until we come to a settlement, if there is a problem. Some people don't take cc because of that.
I have almost 1500 pos feedbacks (one neg from a non paying person), and I have always accepted checks. The only bad check I ever got was a mistake and fixed quickly. Many of my buyers are homebound, and may not have paypal, so checks are how they like to pay.
I agree with the poster who said to check out ebays tutorials...they make it so easy to sell. You should have either a scanner or a camera since without pictures, it's hard to sell items. Priority boxes are free (well, you pay in the shipping, whichmeans your buyers pay) and are ordered on line and delivered to my door. Light items such as clothing mail well in the Tryvek bags, which I also get online (not free). I charge a small handling fee along with shipping, which covers my tape, bubblewrap, paperwork, and other expenses.
Is it time consuming? You bet. I run 50-100 items, daily 9 months a year, and I'm sure hour for hour, I would make more at a waitressing job..but I like to set my own hours, my own vacations, etc. You have to be organized..and if you are selling other than out of your closets, you need to pay attention to income tax. I pay eBay fees, Auction watch fees (they host my pictures and help me keep track), Paypal fees, and vrane fees (they do my return feedback automatically.
A good way to build up quick feedback, if you like to go out to eat, is to purchase restaruant certificates for cheap. A local place we like to eat at is up all the time..and I often bid $1.25 and get it. The place charges a $1.00 service charge. This is for a $25 gift certificate. You pay immediately by CC, and they give you feedback immediately. I would suggest you have two accounts. One for buying and one for selling. Start out selling small quick items to build up that feedback if you aren't going to have just one combined account.
