Our line-item script is working great, but getting persistent InstructionQuotaExceeded errors...

Any thoughts on how to optimize what we thought was a tidy solution to our need to discount products based on tagging? Better ways to simplify these nested loops we need to run? I'm very much a Ruby noob.

#object for lineitem campaigns
class XforYDollarsCampaign
  #array of strings that are substrings to search against product tags
  #int of threshold quantity, ex: 3 items to get the discount
  #cents of pricedAt when matching discount, ex: 1500 = $15.00, so per item will be 1500/3, so $5 per item purchased
  #discount message string
  #matchCount for iterating the cart
  attr_accessor :tagStrings, :threshholdQty, :pricedAt, :discountMsg, :matchCount

  def initialize(tagStrings, threshholdQty, pricedAt, discountMsg)
    @tagStrings = tagStrings
    @threshholdQty = threshholdQty
    @pricedAt = pricedAt
    @discountMsg = discountMsg
    @matchCount = 0
  end
end

CAMPAIGNS = [
  XforYDollarsCampaign.new(["2_for_5"],       2, 500,   "2 for $5"),
