I think you need to say how many Imperial Consigners are currently in game so people understand how the consignment slot process works.. this is my understanding..
10 consignment slots per Consigner..
IF there are 20 imperial consigners in the game, everyone gets 200 consignment slots in total.. this means you can have 200 items dumped on ONE consigner, or 100 on 2 different ones, or in fact you can have 10 items on 20 consigners.. You ARE NOT LIMITED TO 10 SLOTS!!!
The options sound pretty good to me, although it would be nice to see a slight discount for 6 or 12 month subscriptions, after all if I have the money in a savings account I could earn 6% interest.. so could you...
