Michelle Creber (or Apple Bloom as you all know her in the show) has created a brand new holiday themed CD, and in honor of it's release comes a 20% discount on anything you want at her music shop. All you need to do is toss the code jinglealltheway in at checkout for drop in price for your entire order. Support her singing career and get some music in return! Sounds like a win/win to me!
You can find everything right over here!
And have some ponified credit cards as a bonus. I don't know if I'd go with that Discord company, but Equestria Express sounds reasonable.
