Costco is an okay place to work however, As someone who worked for Costco in the past, i think i was getting barely $1.50 more than minimum wage (this was 2015).
Furthermore you have a ton of full time employees who will sing praises about the company. However part timers get shafted hard. Oh you can't work 3 days a week due to school, okay enjoy barely 8 hours a week. There were a lot of people there who had to work multiple jobs simply because they could not get enough hours.
Unless you are fully willing to commit to them it isn't a great place to work.
