Americans are buying more products and services than ever before through the Internet.And experts say the popularity of online sales is likely to spread to other countries.Online sales now represent as much as 10% of all retail sales in the United States.This has led traditional stores to seek new ways to keep their customers loyal.

Lynne used the Internet to buy everything she needed for her wedding and holiday gifts for her husband and stepdaughter.Other than food,90% of her purchases were made on her home computer.“I find that，by being able to go online，choose the things that I need，and have them delivered to me right at my doorstep，I eliminate all the driving，all the crowds，all the noise of that，and I usually get a better selection.”

There are a lot of people like her.Experts say American online shopping hit records in both November and December.57% of Americans have bought something electronically.Store owners worry that this growing amount of online sales will hurt their business.Cornell University marketing professor Ed Melaughlin says they can keep their customers by selling goods like clothing，which buyers may want to see and try on before purchasing.The stores could also offer things that are difficult to ship.Besides，some stores can please customers by offering to repair electronic products.

Bill Martin is the founder of Shopper Trak.His business helps stores learn about their customers.He said，“There is still a lot of emotion in the buying decision，you know，that takes place.Often you need that last sense of‘Boy，this is exactly what I want’ before you are ready to part with money，and you can't always get that online.It's a rather cold process.”

While online shopping worries some business owners，the only worry for delivery services like FedEx and UPS is keeping up with the number of packages. UPS Manager Dana Kline says her company is very busy at this time of year.UPS is so busy that it has filled 55,000 temporary worker positions during the holiday season.
