While overall spending forecasts for the looming season are mostly lukewarm, Forrester is predicting a handsome holiday for e-commerce, with sales expected to jump 16% to $52 billion.

The report, written by analyst Sucharita Mulpuru, says that consumers continue to shift more of their purchases online, with 37% of survey respondents planning to make an online purchase, up from 30% last year. And the Cambridge, Mass.-based consulting firm says that in November and December, online shoppers are likely to spend $338 this year, up from $303 in 2009.

As in the past, this year's online shoppers are more likely to be well-heeled (87% of online shoppers with a household income of $100,000 or more say that they will spend the same or more online this year; just 13% say they will spend less.) Mulpuru also writes that more shoppers are beginning to experiment with mobile technology, with 18% in this survey planning to use their phones to compare prices, and another 16% planning to use them to find stores.
