Wifly shield + weather shield + Arduino red board r3

Hi

I am new to arduino wifi. I bought this module and planned to integrate it with the weather shield. However, I realized it has the original non R3 layout! I cannot put the weather shield on top of the wifely shield! Unless I cut the legs of the additional two legs on the weather shield R3 layout. But doesn’t that defeat the purpose of shields if I want to put something more in between?

Why is the wifi shield esp8266 only $14 dollars while it has R3 layout and can connect to wireless n? While this $69 wifly shield does not? I am new to wireless connectivity so please correct me as logic tells me I may not be correct here.

Is this a good shield for beginners to start with wifi projects?

You can clip them off, it doesn’t look like either shield uses those pins. Or you can use wires to connect the used pins if you don’t want to clip them.
