LOTS of MLM type of things. $5.00 gift cards (like her series isn't going to make that if I have the amount of chapters correct.). she could lose money. Offers of swag like keychains. Games and winnings are suggested. I have to admit, this type of thing is totally out of my realm and not something that I lean towards. Unless a swag bag includes some really good chocolate I tend to turn them down at cons because they just get thrown out.
But... that's me. I lucked permission to promo my series on a Wuxia FB page with close to 3,000 members, that's more my speed.
It will be interesting to see what's going on. In the meantime, buying up those popcorn futures.
