FOR IMMEDIATE RELEASE

PFSweb’s End2End e-Commerce ^® Clients Generate Record Customer Traffic

Volumes During the Period from Black Friday Through Green Monday

- - -

Same-store-order volumes increase by 77% in total sales for Black Friday/Green Monday Period

PLANO, Texas, December 16, 2011 — PFSweb, Inc. (Nasdaq: PFSW), an international provider of end-to-end eCommerce solutions, today announced record customer traffic and order volumes for its North American End2End luxury, cosmetic and apparel clients’ e-Commerce Direct-to-Consumer (E2E DTC) brand sites during the time period starting on Black Friday through Green Monday.

Over the post-Thanksgiving Day period of Friday, November 25, 2011 through Monday, December 12, 2011, including Black Friday, Cyber Monday and Green Monday, PFSweb’s North American luxury, cosmetic and apparel E2E DTC clients’ brand sites received approximately 366,000 customer orders with an average order value of more than $106.00. These clients’ websites also experienced strong customer traffic, with approximately 12 million sessions in total, including approximately 5.6 million new visitors.

Overall, PFSweb’s North American E2E DTC luxury, cosmetic and apparel clients’ brand sites also reported strong same-store-order volumes compared to the similar period last year, including a 68% increase in total number of customer orders, a 52% increase in total number of visitor sessions and a 39% increase in new visitors. Same-store-sales data includes data from the E2E DTC luxury, cosmetic and apparel clients’ brand e-Commerce sites that were in operation during the 2010 and 2011 Holiday season and supported by PFSweb during both periods.

“The Black Friday through Green Monday period has become a major event for PFSweb’s End2End e-Commerce^® clients as they focus more attention towards exceeding the increasingly high expectations of holiday online shoppers by deploying Internet-only promotions, cross-channel offers and special online events. These holiday shopping promotional activities have driven significant customer traffic to our clients’ e-commerce sites generating a higher than expected level of completed sales,” stated Mike Willoughby, President of PFSweb. “While our End2End DTC luxury, cosmetic and apparel clients only represent a portion of our current business, they are an increasingly strong growth driver for PFSweb as we continue to expand the number of consumer brands we support. As our existing client programs grow through increased volume of orders and customer support, so does the service fee revenue for our business. While our client activity is strong, we have also accelerated certain infrastructure investments and incurred incremental one-time expenses during the fourth quarter to

support this higher than originally anticipated growth. While we have implemented cost management measures and are working with our clients to more effectively forecast demand spikes, we currently estimate that our calendar year 2011 Adjusted EBITDA performance will be at the low end or below the previously targeted $6 million to $7 million guidance.”
