Home Depot and other large home improvement stores typically allow customers to purchase appliances like fridges and take them home immediately, provided they are in stock at the store. However, policies can vary depending on the specific store location, stock availability, and other factors.
To ensure that you can buy a fridge and take it home immediately, I recommend checking with your local Home Depot store or their website to verify their current policies and the availability of the specific fridge model you are interested in. You may also want to inquire about any additional services they offer, such as delivery or installation, if needed.
