65% of online shoppers wait a day or more to complete their purchase

"Retailers should re-examine abandoned shopping cart rates. McAfee’s study found that 65% of all shoppers wait a day or more to complete a purchase, and the average delay is 33 hours and 54 minutes. Instead of panicking, e-tailers should understand the reasons for abandoned shopping carts and implement strategies to combat consumer fears.
“Retailers shouldn’t misinterpret abandoned shopping carts – many of these potential sales return later to finalize the sale,” said Keats. “Understanding this delay is critical for merchant analytics.”"
