to another private buyer
afaik the difference between 83$ and 120$ is not "10-15%" either, i did mention non-bulk also
Ok, lets that NM Future Sight Tarmogoyf.
On ebay, the most recent completed auctions for a NM are between 140-160. Let's call it 150. Ebay and paypal take roughly 15% of that, so you lose 22.50. Then, you pay about $2-3 to ship it with tracking at the least, more if you insure it. So, we've 'made' about 125 now.
The highest buylist offer, according to quiet speculation's tool, is $110 and their are multiple offers close to $100.
So, that's about 15-25% extra profit selling it on ebay. But, those shipping fees are a flat value, they eat a much higher percentage of your profit when dealing with lower price cards, such as under $20.
If you only ship in a regular envelope, with no tracking, you can get away with just a stamp, so then your total shipping costs come down about 60 cents per package. But, you also will have about 1 out of 40 packages 'lost' according to the buyer. The post office really does misplace roughly 1 out of 80-100 packages, even when I've used tracking, but whether it's dishonest buyers or the post office being more careless with regular packages, more issues come up.
That's not even factoring the time you spent doing any of this, which becomes a pretty low hourly rate dealing with the sub-$40 cards. Or, the fact that you will NEVER sell 100% of your cards at those prices. You will have some amount left over after however much work you put in, that you then either sell as a lot to someone for less money anyways, or have to buylist.
TCG allows individuals to sell on there, but not everyone wants to be bothered with the effort to make a little bit more money. If their job pays them a 40k+ salary, the difference in profit would have to be over $20/hr for most people to care.
Until two months ago, I was selling on TCG and when you scale it up, those 10-20% profits can be a sustainable business. But, again, not everyone wants to be a mtg vendor, even part time.
