Consumers are cutting back their purchases on eBay ( EBAY).

Purchase amounts are down 30% this year, with customers spending an average of $163.56 during October compared to $232.50 in January, according to the new Main Street Spending Index (MSSI) compiled by Geezeo, a personal finance Web site that helps consumers track their spending.

The number of transactions has remained approximately 2.5 purchases per month; however, the amount spent per transaction decreased significantly from $95.05 in January, to $63.92 in October, according to the Geezeo MSSI.

eBay's competitors, including Amazon ( AMZN), Google ( GOOG) and Yahoo! ( YHOO), are feeling the pain from reduced spending. But while eBay is seeing customers scale back purchases, the overall market for secondhand goods has grown as consumers tighten their belts.

Sales are up at local resale shops nationwide. The national Association of Resale & Thrift Shops says that 62.5% of its members reported higher sales in August, and Goodwill has seen a 6% increase in retail sales for the first seven months of 2008 versus the same period in 2007, according to a report on www.MainStreet.com.

With more people searching for a bargain, spending on eBay may remain deflated until the economy turns. However, given the site's strong customer loyalty and retention, eBay is poised to make a comeback once a recovery is under way.
