If you're not already on eBay managed payments your fees will be going up considerably once you're moved into managed payments. They will be charging a $0.25 PER LINE ITEM fee on each invoice along with their percentage take of your total sale (including shipping). And that's in addition to the regular final value fees.

I've moved over to Delcampe where my fees are only 6.5% plus $0.17 per item (and it doesn't include the shipping cost) with unlimited listings. I have over 22,000 listings that are there all the time. They encourage listing your entire inventory and you can still deal direct or trade off site using their listings. I'm selling slot cards mostly but my sales on Delcampe are at last 100X my sales on eBay where I'm limited to just 50 listings per month unless they feel sorry and give me extras. Plus a store on Delcampe is FREE or you can pay $60 PER YEAR for enhanced features and fee discounts. Added benefit is that the monthly fees are based on your sales total for the month. The more you sell in a given month the lower your fees on everything.

I only use eBay sales now to find new buyers, inserting a flyer about my Delcampe sales and it almost always brings in a new buyer for repeat sales. In reality eBay sales are hardly worth the trouble for me, there's very little sales volume there these days.

Just my 2 cents, it's working for me.
