Please understand the spirit in which this comment is posted. I am not trying to yell at anyone or whinge however, I was more than a little disappointed with the recent blog post about the savings associated with Karl Barth's Church Dogmatics that are on sale this weekend.
The post states at the beginning that we are able to save almost 32% off of the retail price of the set. Fair enough. However, there is no explanation that the retail price is not the so called sale price (which is the regular price). Therefore I went and checked my sums and thought that I could purchase the set within my budget. I turns out this i snot the case and the 32% is the amount off of the retail price even though the second to last sentance of the blog post which states "This week, two years ago, we released all fourteen volumes of Church Dogmatics for Logos Bible Software. We’re commemorating this anniversary by offering a this-weekend-only discount of almost 32% off of Church Dogmatics (14 Vols.)" fails to mention which price the amount is off!
Here are my points:
Firstly, I think it is wrong to over state the discount without an explanation. Having said this I do not think Logos are trying to be misleading however, I do think it would have been better for us customers to read how we're are saving nearly 20% (or whatever it is) off of the regular price we are able to purchase it for.
Secondly, I think the second to last sentence needs to be adjusted. This is the one I read and based my sums on.
Well, there ends my rant. I love logos and appreciate any special but I admit I really got excited when I read 32% off and I assumed it was that amount off of the price I would normally pay.
Please receive this in the spirit which it is intended and not as an attack.

Peace be with you.
