Yes, if you have two MAJORLY different approaches to an essay (ie, two different stories you could tell) and you're REALLY not sure which direction to go, you can send over both.
BUT (and this is a big BUT)...
Bear in mind that this means that in order to read through the extra material, we'll likely need to spend a little less time on some other aspect of our feedback to balance things out to keep things fair as we try to spend approximately the same amount of time across reviews. If this starts increasing, then we'll have to increase prices, and we don't want to do that!
And please don't send us two different essays with just one or two sentences different. Reading through two nearly identical essays and trying to figure out what is different about them is NOT a good use of our time!!
