Or how about just asking LSC to match the price? Here's what they have in their help section of the website:
"Will you match someone else's sale price?
Yes we will. If you find an authorized reseller selling a brand new program at a lower price, we will match their price if you prefer to purchase from us.
Place your order on our website at the price listed. When you check out you will be able to write us a message. Tell us what you would like. Be sure to tell us where you saw or heard the special price so we may verify it.
Someone reviews each order before we charge your credit card."
