Just to clarify a few things
I have a client who did receive a refund and is resident in the UK. However, that was two days after the release of LPX. Since then I understand from two different sources (plus what Pancenter stated earlier in this thread) that Higher Management at Apple have issued a "policy' update to their Customer Service Reps (CSRs) staitng they are not to issue refunds. This policy 'update' applies to all CSRs no matter where in the world they may work and is not just limited to those in the UK. I believe however, that some CSRs in the USA for example.. did not receive this update until several days after the UK ones... which possibly explains why those in the USA continued to be able to obtain refunds for several days before that policy was 'updated'.
It has been said that the terms of the Mac App Store EULA clearly says (and to paraphrase) "No refunds... " but I have not found that to be the case. I have not found any terminology in the Mac App Store EULA that reflects this. There is some terminology in the iTunes Agreements that could represent this policy but again, it is not clear as to if this relates to Mac App Store licences.
If anyone would like to point me to the specific 'no refunds' terminology in the Mac App Store agreement or the section of the iTunes agreesments.. i would appreciate it.
There was a revision made to the iTunes Store EULA in Taiwan in June 2011, which explictly allows refunds during the first 7 days but this revision only applies to Taiwan Residents and no one else.
The revised terminology reads as so;
"You may cancel your purchase within seven (7) days from the date of delivery and iTunes will reimburse you for the amount paid, provided you inform iTunes that you have deleted all copies of the product. Upon cancellation you will no longer be licensed to use the product. This right cannot be waived."
Again, this revised terminology only applies to residents of Taiwan.
Finally, just a matter of fact... You are not buying an app from the App Store.. You are licencing a product. This being so, there are different legal rules in most countries that can and do affect/limit your rights to refunds.
Note: I am not a legal expert in any sense. I am simply stating my own opinons based on my own, personal experience and research... the experiences related to me by my clients... and others here and elsewhere.
