Here's what the result should look like:
Here's the code:
<iframe style="width:100%;height:800px;border:none;" src="//kindleweb.s3.amazonaws.com/app/1.0.11.053.093655/KindleReaderApp.html?asin=B001ULD5PA&assoctag=paycart-20"></iframe>
To embed this for any book, just update the ASIN # (unique for every Kindle book) which appears in the snippet above after the asin=:
asin=
Then paste the remaining:
&assoctag=paycart-20"></iframe>
PS: Did you know Amazon has a trade-in program?
