Do they have copic markers?

Yes they do! The big packs that have 6 markers Are around 60$ I believe ? And the copic sketch markers are a bit less (from what I remember). Single markers are usually by the cashiers and cost around 7-8$ They also have coupons online! Make sure to see if theh have anything

Yes they do! They are behind the counter! They have individual markets @$7.99 and a pack of I think 5 for $36.99! Source: I work there :)
