Instacart is a failsite and I hate it. Tips?

[shoeshine box]

Also what is the proper tip % to leave? It is suggesting 5%. Is that too high or too low? Order is about $150 from each place.

my 2 cents..I am a Sports sport and i would def Do 5 apc.... If the guy was cheerful, helpful, and all went well i might throw him 10...But 5.00$ i "say Thank you sir",..
