Just an idea, but how about a vendor where you could either A) Re-sell gem store items such as 1-permanent passes, 2-salvage-matics. 3-items that can go into your bags for half their SALE price gems, OR allow us to trade them in for a like item for half the price (I.E. trade in a royal terrace pass for a Armistice Bastion pass for 500 gems). Some people are reluctant to buy items because they have excess amounts or already own a like item. This would give them options where they would have an incentive to spend more Gems.
