Hi,

Sorry I was not paying attention about the ongoing PR (https://github.com/jef/streetmerchant/pull/1479/files) about the equippr/futurex store. I added the futurex store in this PR and also fixed the lint errors which were caused due to encoding / formatting problems. Hope this is ok for you @Doerster and @jef.

Cheers and merry christmas.
