Korg have a promo on in the US only sadly: Buy any colour Monologue from participating dealers between September 1st to 30th and get a free Volca Kick.
They are billing it as "one powerful rhythm section"
To help you hold down the low-end, we’re giving away an all-analog, MS-20-inspired volca kick with every new monologue analog synth purchase. Both feature sync-able step sequencers, tons of analog tone, and hands-on sound shaping to help you lock in powerful rhythm sections.
The offer is running on the Korg Website, where you can find a participating dealer and also redeem the offer.
Korg Monologue is priced at around $299 US., The Volca Kick at around $175, so thats a pretty healthy offer.
