Non-Custom-Furniture Returns & Cancellations:
How much time after I purchase do I have to cancel for a refund?
There are no cancellations or refunds for any order under any circumstances for any reason. If an item arrives damaged or missing parts, Colby and Madilyn Hawkins will work with the manufacturer to provide you parts or a replacement as quickly as possible.
These terms are posted on each product page, on our home page, and require customer consent during checkout and prior to a purchase.
Immediately after placing an order our suppliers go to work getting your order out the door. Due to this, orders can’t be changed or canceled. However, if it arrives damaged or missing parts we get you replacement(s) free of charge, of course!
In extenuating circumstances, customers may cancel an order within 24 hours of purchase via texting 916-692-0554 or emailing sales@hawkinswoodshop.com for store credit.
Will you refund me back onto my card?
Never will an approved order cancellation (one that is done immediately after purchase) be refunded back onto an original payment method. All approved cancellations done prior to receiving an order confirmation by text or email will be refunded back via store credit within 2-3 business days.
Again, once a purchase is confirmed, even prior to shipping, there can be no cancellation under any circumstance and for any reason.
How much time after receiving my non custom order do I have to ask to return the item?
We do not accept returns for any reason. If a product arrives damaged/missing parts please contact Colby at 916-692-0554 or kindly email sales@hawkinswoodshop.com. Rest assured, we'll help get you a free replacement or free delivery of any missing parts.
Shipping delays or other factors beyond our family's immediate control do not constitute grounds for cancellation or a refund.
Thank you for your patience and understanding if we experience a hiccup with your order's supply chain.
Orders lost by a carrier are not grounds for cancellation. All lost or damaged delivered orders will be replaced free of charge.
American Made Custom Solid Hardwood Furniture Returns & Cancellations:
We sell locally handmade built-to-order furniture here: https://hawkinswoodshop.com/collections/customorder.
Given its hand made and hand-finished nature, variations and imperfections in solid, real-wood furniture are to be expected and celebrated. Each item is an original and no two pieces are exactly alike. By their nature, wood planks may be somewhat uneven and may develop small cracks and cup or bow over time due to changes in temperature or humidity. We believe this only enhances the furniture's rustic, unique character.
There are no cancellations or refunds on built-to-order furniture.
There are lots of reasons we have so many 5 star reviews from customers. Perhaps the biggest reason is we LOVE our customers! We work until you are completely satisfied, & offer a 100% satisfaction guarantee at time of delivery or pick-up.
In conclusion, when you buy from a small business, you're not helping a CEO buy a 3rd holiday home. You're helping a little girl get dance lessons, a little boy his team jersey, and moms and dads put food on the table.
Thank you for your support. Thank you for following our social accounts and commenting on our posts. Thank you for telling your friends about your purchase today. And if something goes wrong with your order, thank you for your patience while we work night and day to make it right.
