The humble receipt gets a redesign
Here's my opinion:<p>What she got right<p>- see items within categories from most expensive category to least, each category showing a percent of your total grocery bill<p>- see relative price within a category at a glance (even if you buy wine, that's within your alcohol category, so it won't mess up the relative pricing of your dairy or snacks)<p>What might not go so well<p>- the bubble chart is less universal and intuitive (and it's "quirky")<p>- does volume (of what's printed) matter for thermal printing costs?<p>- would waiting to print the receipt at the end cause a big slowdown vs printing as you ring items up? (I believe with most current systems, items can be added and removed, and they show up as 'add' and 'remove' line items, because it does print as you scan.)<p>Many people mentioned digital/CSV breakdowns. I know Home Depot quietly connected my credit card to my email address after asking me if I wanted a digital receipt, and I typed in an email. So this seems like a reasonable option, for anyone that grants permission. (Home Depot annoys me because I say "Yeah! E-mail me!" and then they hand me a receipt anyway. Ungh!)
