I wouldn't know about that as I do not own a vita, but they did mention that 59,99$ games wouldn't see a price increase (said it again for Second Son).
Also, they are the only canadian store (that I know of) selling Yoshi's New Island for 40$, so up to this point, I do trust them.

and they've said on twitter that they won't be increasing their prices. Even if they charge 4.99$ for shipping on some items, I'd rather pay 65$ for that than 65$ to ebgames.
