Read on for what we think are key takeaways from holiday seasons past:For swoon-worthy sales, online-only retailers may be your best bet. During holiday shopping season last year (October through December), online-only retailers were discounting at an average of 45.7 percent, with Specialty Retailers at 45 percent. Department store discounts lagged at about 41 percent.The deals may be even better for Holiday 2011, if discounting trends so far this year continue. To date in 2011, Online-only retailers are averaging 47.3 percent off womens items, compared with 45.9 percent off for Specialty retailers and 43 percent off from Department Stores.Expect deeper discounts than last year. Overall, womens discounts online across all types of retailers have become steeper in each of the past two years. For example, summer season discounts in 2009 averaged 41.9 percent; in 2010, discounts jumped to 45.8 percent off; and this summer, they reached 47.0 percent off.But, dont hold off purchases, expecting this trend to continue.
