KyoDiscounts XP VX, ACE MV

[kyonides]

Well, I decided to post the latest version of KyoDiscounts XP 1.5.0, even if it is some sort of beta release.

Edit: I had to include some method calls to get rid of the appraisal options window and the appraisal result window contents.
Another Edit: I had to reduce some windows sizes to fit the screen... =_=

Code:

# * KyoDiscounts XP
#   Scripter : Kyonides-Arkanthes
#   v1.5.0 - 2019-01-13

#   Whenever you obtain a discount card, such discount will be applied to all
#   of your purchases if you have picked a card till it expires after a certain
#   number of steps. Additional steps will be quickly added to your current card
#   whenever you purchase any additional card of the same kind.

#   One coupon will be spent every single time you purchase any specific item,
#   you will need another one to purchase a different item later on.
#   The discount card or coupon price is used to calculate the corresponding
#   discount on every single purchase the player makes with it.

#   Place this script below KItemRefill XP or KyoScriptPack Item XP if you
#   included any of those scripts in your current game project.

#   Now you can also setup exclusive store discount cards as well. Just keep in
#   mind that you will need to setup the in game variable you picked so it will
#   be able to store the Exclusive Store Code (an Integer) before you can add
#   the shop event command. Common stores don't need any Store Code at all.

#   Besides the player can also place orders to get an item that is supposed to
#   be found at another store only. The player will be charged an extra fee, but
#   he or she won't need to go back to another store. The player would only need
#   to keep walking for a while before the goods are available at the store.
#   Now the required steps for each placed order will be automatically increased
#   between 0% and 50%, making it look a bit random but also kind of realistic.

# * Unknown Item or Weapon or Armor Appraisals *

#   Use the Game Variable defined in the STORECODEVARID Constant to store the
#   Shop ID that will include the appraisal service.
#   Use the MYSTERIOUS series of Arrays to include as many IDs of unknown items
#   or weapons or armors that will serve as fillers till they get replaced by
#   the actual goods they represent.
#   Follow the Instructions included in the APPRAISALS Hash to define all
#   conditions that will affect an appraiser's task of identifying the item.

#   Script Calls   #

#   $game_party.discount_cards_expire
#      Makes all Discount Cards expire as part of the game's plot.

#   $game_party.disc_card_expire(Card_ID)
#      Makes an specific Discount Card expire as part of the game's plot.

#   KyoShopOrders << [Percent1, Percent2, etc.]
#      Defines a Commission percent for every Item in the Place Order List.

#   KyoShopOrders.steps = [Steps1, Steps2, etc.]
#   KyoShopOrders.steps += [Steps5, Steps6, etc.]
#      Defines Steps required by every Order in the Place Order List.
#      The 2nd call will be required only if you couldn't include all steps.

#   KyoShop.scarcity_lvl = 0 or higher
#     Define all prices and maximum number of units per shop item.
#     0 means no scarcity, 1 or higher reflects how severe it is.
#     You also have to configure the @scarce_limits hash in order to predefine
#     :price and :max per scarcity level. The maximum scarcity level depends on
#     how many values you entered in both :price and :max arrays.
#     In few words, you define the maximum scarcity level ever possible!
