We'd like to share some information with you to help you stay updated with what's going on at Life and Home in the coming days.

Steps We're Taking:
Our offices are all currently set up to work from home to help stop the spread of COVID-19. At our warehouse, we are increasing efforts to disinfect high-touch and high-trafficked areas throughout the day and increasing daily cleaning routines. We are also making sure all employees have up-to-date information on how to stay healthy and what preventative measures should be taken and the ability to stay home if they are feeling unwell.

Updated Return Policy:
We have temporarily updated our return policy from 30 days to 45 days. Our goal is that you're completely satisfied with your purchase. If for any reason, you are not satisfied, simply return your purchase in its original packaging, with your original receipt/email confirmation within 45 days from the purchase date.

You may experience delays in shipping as we are taking the necessary precautions to protect you and our team. We are still working hard to get in-stock items shipped within 24 hours. Few items may temporarily have longer fulfillment times.

Customer Service:
Our customer service team is working hard to help all customers as quickly as possible. Due to technical difficulties, you may experience interrupted calls. In the event this occurs, please email us at or message our chat here on the site. We apologize for any inconvenience and thank you for your understanding.
