Mother’s Day may be considered a “Hallmark Holiday,” but that won’t stop consumers from showering mom with gifts on May 8. According to NRF’s 2011 Mother’s Day Consumer Intentions and Actions survey, conducted by BIGresearch, the average person celebrating the holiday is expected to spend $140.73 on gifts, up from $126.90 last year, and a return to 2008 spending levels. Total spending is expected to reach $16.3 billion.
