I was a sam's club member years ago. Now I remember why I never renewed my membership. My online order on 11/11/17 originally had a delivery date of 11/16. I checked the order status every day and the date moves... now it's 11/29. You're better off getting it in store if it's available. If it's not available in store, just know that you may or may not get your order in time for your planned trip, gift, etc. With my last membership that I had years ago, I was promised that my "in store pick up" order would be available within the day. I ordered that morning. In the evening, 2 hours before store closing, I went to the store to pick up my order and was told my order wasn't ready for pick up until the next day. I just cancelled the order and make the purchase in store. Basically, I wasted so much time ordering online for in store pick up, which was supposed to be ready for me to pick up so I don't have to come and shop. I never renewed my membership because I don't really care for their bad customer service. This year, I decided to give them another chance, hoping that their customer service is better. It is NOT. I ordered my Segway MiniPro on Nov. 11,2017. They gave me an estimated deliver date of 11/16. Then it moved to 17, then 20, 21, 22, 27, 28, now 29. Every day I check, I get a later delivery date.
This explains why every time I actually visit their store, I never have any problem finding a parking spot near the entrance. Their parking lots are always at least half empty every single time I visit them whether it's near opening time, in the middle of the day, or near closing time.
Costco, on the other hand, is the membership I have kept since 2000. Whenever I order something online, I ALWAYS get it earlier than their estimate date. For example, when I order the iPad Pro 10.5 from them on the 9th, I got my order on the 10th even though the estimate was 3-5 business days. With Costco's estimate, I wouldn't have receive my order until at least 11/14. Their customer service is also top notch. That is probably why whenever I visit a Costco store, I almost always have trouble finding a parking spot or wait for someone to leave before I could even park.
