I usually shoot on a neutral grey backdrop and overlay a texture from my texture library in postproduction. This works really well. However, cutting out and overlaying gets very time consuming when there are lots of images to process.

I recently tested out a relatively inexpensive backdrop from a company, and made an unboxing video with pros and cons. The company liked my video and have offered for me to give fellow photographers 25% discount voucher code (probably UK only)  I am happy to share the link to the video and the discount code, but have no wish to be seen as spam.  would this be the appropriate forum to post such details?
