The extension is available on Chrome, Opera and Firefox (see installation instructions below).
Batch Buys from the market
Once the extension installed/updated, navigate to our market as usual and select a card to buy.
SteemPlus will modify the UI to enable the Batch Buys :
From there, you can either handpick the cards you want to buy, or use one of the four filters on the bottom of the page : All, None, X Cheapest cards or Up to X$.
You will then be redirected to a SteemConnect page to validate the transaction. SteemPlus will add Steem Keychain compatibility soon.
Note that the transfers might fail if the memo is too long (more than 45 cards at a time).
