How pickup times work
Choose your preferred times
When creating your ad, select the times that work for you.
The more times you add, the higher the chance that a helper can come.
You can only select times for the same day or the following day.
Helpers can suggest other times
Helpers can send their own time suggestions outside the times you selected.
You decide whether to accept them or ask for a new suggestion.
Tips
Add multiple possible times if you want to get help faster.
If you’re flexible, accept alternative time suggestions to complete the ad more quickly.
