I'm not sure if this is just a limitation on my system, but it is quite hard to read the sample pages in the store. I used to be able to click in the upper right hand corner to enlarge (large enough to read) the sample. I no longer see that option and consequently all I really see in the sample is the paragraph in a font that is very small. When I do a "CTRL +" the webpage gets larger, but the sample page does not. If I cannot see (as in a readable fashion) I probably won't buy that resource and since it doesn't work on any of the resources that I've viewed in the past few days that will probably save me a lot of money!
Assuming you are talking about the logos.com website, you should post in the Logos.com forum, so the right people will see your post and respond accordingly.
Additionally, I would 1) supply your OS and browser, and 2) provide a link to a product page where you are experiencing this issue, and, if possible, provide a screenshot of the issue.
