In some cases jewelry can’t be posted to the external marketplaces as eBay, Amazon or Etsy exactly at the scheduled time. Valigara will keep trying until it succeeds. Posting tolerance defines the precision in time, how  your items should be posted. The system calculates the difference between the planned time and the current time and stops once the difference is larger than the defined posting tolerance. 

For example:

Scheduled posting time to eBay: 18:30

Posting tolerance: 60 minutes

Valigara will retry posting your jewelry till 19:30, and stop pushing your jewelry to eBay at 19:31
