We’ve recently received a number of requests to apply expired Perks to orders. Please note that Posh Support cannot do this. We ask that you and your customers keep track of your Perks in your Perks dashboard to see how many you have and when they expire.
Certain Perks have different expiration dates based on when and why they were issued. Perks for purchases are good for 1 year, and Perks earned for your birthday, hosting, gifted Perks, etc. are all good for 6 months. Please visit our Perks page for full details.
Thank you for your understanding.
