CUMMING — Retailers are busy this week helping Forsyth County residents prepare to put on their spring fashions, head to church and gather for Easter dinner Sunday. According to a survey conducted by the National Retail Federation, the average American plans to spend about $137 on apparel, food, candy, gifts and more this holiday. That’s slightly less than the $145 spent in 2013, with total spending for the nation this year expected to reach $15.9 billion.
