Due to popular demand, and the fact that Herons Unlimited growth means I need more DEC, Ottermaker is selling Splinterlands Beta packs again. The price has gone up a bit - now 1800 DEC - but the process remains the same. Just send DEC to @ottermaker on Steem-Engine and it will send you 1 BETA for every 1800 DEC you send, plus change if necessary.
I bought 1150 packs for this, so they should last a little while at least.
