BOGOS: Free Gift Bundle Upsell

First the positive , It works after a bit of fiddling and trial and error.
Now the less positive, the install is messy as you need to let them do it really and they make loads of changes to the theme which frightens me.
Support is slow too taking about 20 hours for a response for me on a question.
Finally and most importantly it is ridiculously priced. I have to pay $40 / month for this app. No idea how they can justify the price as I don't see where the ongoing cost is to justify the exorbitant prices. I have great apps like Yo for $6 and Also Brought for $5 and Live Search for $4 all great useful apps. How this app can cost $40 is beyond me.
Luckily alternatives are appearing which will normalise this quickly I'd say.
