Pretty easy to use and install. Seeing the data presented was an awesome year end review. It also helps us justify the executive membership on-demand, without having to ask costco staff to check. For those who are not used to using chrome extensions, top right of chrome browser > click on the puzzle piece, find cartology and pin. Now you can see the cartology icon. Click on it now and walk through the steps to load the data. Requires login to costco website. One feedback to the Andrew would be to provide an option to group and exclude auxillary fees from the highlighted data. It shouldn't be one of the top 10 items you have purchased basically (as bottle water might one of the top 10, these took up two slots of the 10 as it is related). We can still include the data under Auxillary fees category. Example would be: Enviro Fee CL, Deposit Cl etc. Thanks!

I love this! Seeing my stats at Costco for the year is so fun, and it was super easy to get set up! Minor suggestion: I would appreciate an option to my stats without gas station visits taken into account or separate gas station visit stats and in-store purchase stats. Thank you!
