If you've lost or can't find your receipt for the Miroir Micro Projector M20, don't worry! Here are some steps to follow:

1. Check with the vendor: The first step is to contact the vendor from whom you purchased the product and ask if they have any record of shipping it out to you.

2. Look in old emails: If you bought it online, check your old email inbox for a confirmation page or receipt that may contain details about your purchase including order number etcetera because sometimes these documents end up buried deep within our overflowing inboxes so take some time searching through them carefully before giving up hope entirely as they might still be there waiting to help you out.

3. Check with Miroir customer service: If the above steps don't work, contact Miroir's customer service department directly via phone call or live chat (if available) and provide them with all necessary information such as your name address email ID etc., They should be able to look up your purchase history based on this info.

4. Check Amazon if purchased from their store: If you bought it directly through the Miroir USA Store on Amazon, log in to your account there and navigate to 'Your Orders'. You may find a record of your purchase including an order number which can help with any future claims or queries related to returns/exchanges etc.

5. Check other online platforms where purchased from: If none of these steps work out then try contacting the specific platform (e.g., eBay, Walmart) through their respective customer support channels as they too might have records stored somewhere in case you need them later down the line for any reason at all.

6. Contact Miroir directly if nothing else works:

Remember that a valid proof of purchase from an authorized reseller is usually required to make a limited warranty claim, so it's essential to keep your receipts and other documentation safe!
