It's my favourite shop in the World. My parents go there weekly and it's like a fun day out. (We also go to Makro and it's very poor in comparison, costco is like a lifestyle shop as well as a bulk buy trade place).
Amazing food counter as well! ahh I love it. They have the best product buyers, great warranty, fantastic customer service, knowledgable and happy staff, free samples, new products, great prices, amazing food, nice car park.
Once I went to one in LA and it was even more incredible.
