Online shopping is discreet, easy and fast. It's no wonder shoppers are filling up virtual carts instead of visiting brick-and-mortar shops.

Shopping online allows us to skip the lines, crowds, travel expenses and the hassle of parking. A recent survey conducted by Lab42 — a market research company — found 66% of consumers prefer web retailers. About 73% of survey participants complete nearly half of their shopping online.

Savvy shoppers are also turning to web and mobile stores for bargains. Nielson recently reported nearly 50% of U.S. smartphone owners are using shopping apps each month, frequenting eBay, Amazon, Groupon and LivingSocial's mobile stores. About 45 million smartphone owners access shopping-and-commerce apps each month.
