A lot of Sellers complained about the economic slowdown this year. I'm glad to see you're back to listing new items, that should help increase sales. If you list them more evenly, say one a week rather than in monthly batches, it works better because the eBay algorithm seems to reward consistency.
Also it's good to check Complete Listings so you know if your selling expectations are realistic. If only one is sold in the last three months, then you know you have to be patient... even if yours is the cheapest. And if the item is more popular but yours costs 150% more than the cheapest sales, again you know you will have to wait for the right Buyer to come along. Good luck with your selling!
