Instacart app is designed for corporations, not people. It is full of glitches and poorly vetted, slow in responding to complaints with improvements. This is why Instacart phone customer support has had to be so excellent. Instacart touts all the time the hours it saves, yet the shopping experience online lags during peak hours. It is terrible for the URL shopper as well, who often cannot see notes or is confused by lack of sync between notes and replacements. Items are > $$$ as well.
