I moved this to the Partnership discussion forum. ^_^
A couple, but at my channel size (about the same as yours), I'm not really at the size where "flooded with offers" is going to happen yet. Mostly, I've heard from hair care products (very small companies) who would like me to review their products. A couple of companies have sent me some free products after I did an unsolicited review (I got some hair ties and a few hair brushes).
For my cooking videos, I was approached by a subscription service (where they send you food to cook, kind of like Blue Apron, but a smaller company) and a utensil company. I passed on both of those.
I was approached by BBC Ireland to possibly use my long hair videos in a talk show, but they decided to go with someone else. That was sad. I would have really liked that.
Yes - several times. Different types of products - backpack, headphones etc. We do it for free (if we like the product of course) as our channel is too small to ask for money and we always include disclaimer - viewers must know that this is a kind of payed endorsement (we do not get money but we keep the product which costs money).
I got a few emails from companies that promised me to "give your channel exposure" if I did content for them, too bad payment in exposure has been well debunked a while ago. But I also landed in a games publisher's mailing list that means I receive game keys every so often. Among them I discovered a few neat titles
Game keys (or serials) are basically codes that you can redeem on websites or other platforms that sell games on exchange of a game. A bit like Amazon promo codesNot a big gamer, what are game keys? Sounds interesting!
