@A13ssandro put this together today. We bought a few black Friday deals and used it to create a promo for our own black Friday deal.
It started with wanting to just make an image to promote our offer, then figured there were good deals on mock-up tools. That escalated into mock-up video + some music.
The result: https://youtu.be/vtlmXdibiR8
Oh and the offer is € 240 credit. It looked like everyone was doing percentage discounts on their monthly prices, so we thought this would be a bit more fun.
