If you want to be able to take advantage of the Monarch low price but also procrastinate a bit before pulling the trigger, you can use the "save quote" feature of this vendor. Register, set up the order and then save it. Note: the quote option only shows if you register and are logged in. Then you have a week to decide whether to actually buy it at this saved price. This is particularly useful with Monarch, because they have a practice of slashing prices at odd hours, but then they take the item back to regular price after only a few hours. Don't ask me why.
Also, my regards to OP; I think he's figured a way to make competition work for us on some great memory. Ok course, now I have to see if I really need another gig of corsair.....
