New York -- The initially predicted “super weekend” (Dec. 21 and Dec. 22) will now become a “monster weekend” for brick-and-mortar stores, according to RetailNext, whose analysts predict a low single-digit uptick in traffic for brick-and-mortar stores, which will translate into an estimated 5% sales growth this weekend, resulting from improved conversion. The impact of last weekend’s snowstorm, coupled with the online shipping cutoffs, makes this weekend for brick-and-mortars even more substantial.
