ISSAQUAH, Wash. — PCC Natural Markets, Seattle, which operates nine natural foods stores, has begun installing electronic point-of-purchase (epop) signs in lieu of paper signs in a deli case at a store here.

More than 100 epop signs, showing product name, price, description and ingredients, will be installed in the case alongside of products over the next week, said PCC spokeswoman Diana Crane, adding that one sign will monitor the case's temperature.

The signs, measuring 4 inches by 3.5 inches, are from ZBD, Windsor, UK. The signs will be installed in one other store's deli case, said Crane. PCC also plans to test electronic shelf labels from ZBD in Center Store aisles next year.

"Implementation of ZBD's epop solution promises to help us take another step towards better serving our customers with current, best-available prices and most up-to-date product information, and towards optimum use of store staff skills," said Tracy Wolpert, PCC's chief executive officer, in a statement earlier this year.
