Inventory Spy was just the app I needed. By the way, what does the setting ''Show Totals Next To Inventory'' actually means? Keep up the good work!

This isn't working. It only shows 1 quantity for inventory. I have latest version of Chrome how can I get help with this?

Developer fails to mention in the overview that in this free extension you only get 5 clicks per day. Any more than that requires purchasing a "subscription" costing $9.95 (One time? Per year? Per month?) Seems to be a deceptive start which doesn't inspire confidence in an extension which Chrome says can read and change data on potentially every page you visit.

I've found this to be the best inventory checker available. I use it hundreds of times per day and it's much more reliable and quicker than what I was using previously - How Many. I've switched my subscription over to this one.
