I frequent a couple of Ace Hardware stores in my area. This comment is about the wonderful customer service experience I encountered today at MacKay’s Ace Hardware store in Westford. On April 25th I purchased Step 1 of Scott’s 4 step fertilizer for $99. Then today, my wife suggested that I go back and purchase the other three steps because the four steps were on sale for $229.99. I explained my situation to two very helpful staff members and was quite surprised and pleased when my previous purchase of a Step 1 bag was treated as a return. I received a credit for the earlier purchase and then proceeded to purchase the complete 4 step program, a purchase I do not routinely make at the sale price of $229.00. THANK YOU TO THE TWO SALES REPS WHO TOOK MY ORDER TODAY AND SAVED ME A LOT OF MONEY IN THE PROCESS!
