I repeat, the Apple policy is that all sales are final and after an app has been bought and downloaded, there are no refunds. Period.
The ONLY exception to the No Refund policy is if something freaky happens and you buy an app and between your purchase and attempt to download the app it is removed from the iTunes/MAS and is no longer available.
PAYMENTS, TAXES, AND REFUND POLICY
You agree that you will pay for all products you purchase through the Services, and that Apple may charge your payment method for any products purchased and for any additional amounts (including any taxes and late fees, as applicable) that may be accrued by or in connection with your Account. YOU ARE RESPONSIBLE FOR THE TIMELY PAYMENT OF ALL FEES AND FOR PROVIDING APPLE WITH A VALID PAYMENT METHOD FOR PAYMENT OF ALL FEES. For details of how purchases are billed please visit http://support.apple.com/kb/HT5582.
Your total price will include the price of the product plus any applicable sales tax; such sales tax is based on the bill-to address and the sales tax rate in effect at the time you download the product. We will charge tax only in states where digital goods are taxable.
All sales and rentals of products are final.
Prices for products offered via the Services may change at any time, and the Services do not provide price protection or refunds in the event of a price reduction or promotional offering.
If a product becomes unavailable following a transaction but prior to download, your sole remedy is a refund. If technical problems prevent or unreasonably delay delivery of your product, your exclusive and sole remedy is either replacement or refund of the price paid, as determined by Apple.

If you have found a developer whose product you have purchased through the iTunes/MAS who will personally give you a refund, more power to you. That is beyond the scope of Apple's policy and between you and the developer only.
It's time to stop beating a dead horse and move along.
