Thanks for all the info and tips everyone! I had noticed Costco accepting discover online but had assumed that it would code as "online" or something similar, plus they didn't have Disney cards when I checked last week but I'll keep my eyes peeled for them and other cards I can take advantage of.
Gas I was entirely unsure as 99.99% of the time I'm buying gas at Costco unless I'm on a road trip and even then it's still going on citi Costco for gas anyhow. Looking forward to stocking up!
