I recently visited Costco on 59 to activate my new membership. The older gentleman who helped me…read morewas very thorough in explaining the membership benefits and took the time to answer all of my questions. The process went smoothly, and I appreciated the excellent customer service during the membership setup. At the time, Costco was running a promotion where opening auto-renewal would qualify me for a $50 Shop Card. I received the card by email about a week later and decided to use it during my first grocery purchase. Unfortunately, my checkout experience was disappointing. I wasn't aware that the Shop Card needed to be scanned before applying it to the transaction. When I tried to use it, the cashier seemed frustrated and commented that he would need to void the transaction and wait for a manager. Another associate grabbed my cart and started putting items onto the conveyor belt quickly, and I wasn't sure which items I should leave in the cart. While I had a great experience setting up my membership, my first grocery shopping experience at Costco was not what I expected. I hope the checkout process can be handled with more patience and better communication, especially for new members who may not be familiar with how everything works.
