TypeError: can't cast Array to string

I'm getting this error when trying to run a rake task using Nokogiri.

This is the code.

namespace :tops do
  desc "Get Tops Description"
  task get_description: :environment do
  require 'nokogiri'
  require 'open-uri'

 doc = Nokogiri::HTML(open("http://ift.tt/1qTzPZX"))

  price = Array.new 
  items = Array.new
  brands = Array.new
  sale_price = Array.new
  image = Array.new
  item_url = Array.new

  price = doc.xpath("//del").collect {|node| node.text.strip}
  items = doc.xpath("//div/a/h4").collect {|node| node.text.strip}
  brands = doc.xpath("//span[contains(@class,'vendor')]").collect {|node| node.text.strip}
  sale_price = doc.xpath("//span[contains(@class, 'price')]/text()").collect {|node| node.text.strip}
  image = doc.xpath("/div/a/img/@src").collect {|node| node.text.strip}
  item_url = doc.css('div.details a').map { |link| link['href'] }.collect 

  price.each do |prices|
      Tops.create(description: price)
    end
  end
end

This is the full error.
