Business network CNBC is reporting new analytical data made available by Slice Intelligence indicating that Amazon captured nearly 31 percent of all online spending for the period spanning the Thanksgiving through Cyber Monday shopping days.

If this trend is corroborated by other reinforcing market intelligence data, it would represent yet again the significant online dominance of the Amazon shopping platform. Keep in mind that we still have another 22 days of shopping activity remaining before the celebration of the Christmas holiday and Amazon’s reach could well expand.

Other noteworthy findings indicate that online sites of Best Buy and Target Stores made significant online sales gains while Wal-Mart’s online site fell back in the rankings despite having a record number of initial visits.  Macy’s suffered a significant site outage for much of Black Friday and that was reflected in online sales performance.

Data related to just the Cyber Monday period provided by analysis firm ComScore indicates that Amazon, EBay, Wal-Mart, Kohl’s and Target were the most visited retail sites among shoppers utilizing desktops and mobile devices.

The CNBC report further points to major retailers seeing an uptick in the number of shoppers electing to take advantage of the in-store merchandise pick-up option.

Last year, online shoppers waited until the December period to make their purchases, hoping to snag more attractive merchandise discounts and promotions. Going into this year, retailers have generally cut-back on overall inventory investment with the implication that consumers may well experience some stock-out conditions for the most in-demand merchandise.
