You can do this.. but you cannot say "we charge you 30% more here, but if you signup over there, it's regular price"
Apple saying "it's giving the users more options" is total BS.. it's all about getting their 30%, because if you play by their rules, and give the customer more knowledge that you're being forced to charge extra because of this payment option.. then Oh noes.
A great example outside the app store is some credit cards charge much more than the others, so some stores charge you that on top. "You want to use X card, sorry but there's a surcharge for that card.. you could use something else.
And most importantly, you're not actually allowed to communicate what the actual price of the service is. So any customer who doesn't look up the pricing on their website will think that it's $142 a year, not $99 a year.
