I put considerable effort into researching carts, as the first one I purchased from Staples was a “Smart Cart” and it fell apart after only three uses. Keep in mind, it fell apart walking home on a major street after a visit to the grocery store! And it was NOT overloaded. Just poor design, although it looked cool. But I didn’t look or feel cool trying to drag my groceries home in a broken cart. Now, the Sandusky cart, I LOVE. The wheels are rubber, not plastic. The frame is pretty sturdy and it was surprisingly easy to put together. The only glitch was that it was shipped missing two of four “pins” needed to put it together. Grrrr. But I looked up the company online, called the customer service number and boy, was I surprised. I mean, this almost never happens, folks. I received the most excellent customer service. I mean like from the days of yore customer service. I was flabbergasted! They overnighted the missing parts. They followed up by phone to let me know they had been shipped and to expect it the next day. The women I spoke with on the phone were genuinely kind, concerned for my dilemma and willing to help. What?!?! It was outstanding!!! I cannot speak highly enough of their customer service department. They turned what could have been a bad experience into a good one. And I love the cart. Often I am asked where I got it, because oddly enough you cannot find a store that carries carts in Phoenix. I even checked Walmart and I hate Walmart. So when people enviously eye my cart and inquire as to it’s origin, I tell them my story as I am telling you now and all are impressed. Seriously, customer service is a lost art. Good job, Sandusky! Thanks Amazon. 🙂
