We have a 30-day return policy, which means you have 30 days after receiving your item to request a return.
To be eligible for a return, your item must be in the same condition as you received, unworn or unused, with tags and in its original packaging. You’ll also need the receipt or proof of purchase.
To start a return, you can contact us at email@example.com. If your return is accepted, we’ll send you instructions on how and where to send your package. Items sent back to us without first requesting a return will not be accepted.
You can always contact us for any queries at firstname.lastname@example.org.
As our shopping cart automatically calculates shipping charges when placing an order, in some cases the shipping charges are not final; they are only estimated freight charges. Overweight and big-volume products require higher shipping and handling charges. Customers will be notified of the exact shipping charges via email or a phone call for approval of the new shipping charges. DR Instruments reserves the right to cancel any order that does not get the customer’s approval.
