Hi, We keep our prices as low as possible year-round, so other than bulk discounts, we don't tend to discount, and do not "play games" with pricing - we keep it as straightforward and honest as possible. To discuss package pricing, please just give us a call at 877-889-4685 M-F 8-5 Pacific. You can purchase anything on the site with rewards dollars; they work like cash. We can discount panels in bundles, but as an example, you would have $90 in rewards dollars from the castle purchase, which could then be applied to the panel.
