Ebay analysis

Since I started the fund raising period about a month ago my Ebay here is the breakdown of what i've made:

DVDs sold to date - 80 DVDs out of 300+
Total Ebay Revenue - $598.00
Ebay Listing fees - $333.00
Net Ebay profit - $265.00
Net Ebay profit per DVD - $3.31

Is it worth it yes. I was only offered $1.00 to $1.25 per DVD for the entire collection. But I guess if you factor in the gas costs of running back and forth to the post office. It might not be worth it, but im enjoying it. I was able to cut down on costs and buy shipping envelopes in bulk to save $.50 per envelope. I hope to raise about $700 to $800 more so it will pay for the projector.
