This week's free store item is a Potion of Rapid Crafting using the code CRAFTMOR. For 60 seconds, you can craft an item in half a second, meaning you can do up to 120 items in a minute. Be sure to check that you have the mats, that your tools are repaired, and that you have space in your bags for the output.
Since the Mordor expansion will add a crafting tier, if you need to level up crafting, using this with a +100% Craft XP Boost will help.
