How to clear inventory

[Goowie]

Is there a way to clear my inventory so I can put in my new melee weapon, also I got this thing out of daily rewards and got something making platinum prices 50% off. How do I equip/use this?

The 50% off is already in effect on your account, just visit the platinum store.

Also, what do you mean by clear your inventory? What do you wish to get rid of?

I assume you mean sell stuff like spare Blueprints, weapons you don't use and whatnot?

Escape -> Equipment -> Inventory

It's for buying Plat from the website:

Are you talking about not having enough weapon slots so you can't take your newly built melee weapon out of foundry?  You can sell your weapon in the Inventory section of your menu.  I recommend that you don't sell quest rewards because right now many of the rewards can't be gotten again in game.  I also recommend for the weapons you don't want to keep that you level them up to 30 before you sell them.  I would check if some of the weapons are required to build new weapons before you decide to sell them (weapons as crafting material).  

It's lucky you got 50% off plats.  Perfect time to buy some plats so you can buy more weapons and frames slots. :D
