Our shipping costs are “Live Rates” – that is, when you put in your zip code, our website requests the current rates from USPS and UPS to ship from our fulfillment center in Denver, Colorado to you. There are a number of shipping options to choose from on the checkout page.

The cost you see is the cost we pay to ship your items, we do not charge any overhead. We apologize for not being able to offer lower-cost shipping than what USPS and UPS charge us. Small businesses like ours do not have the ability to create our own shipping fleet like some of the larger booksellers.

Specific Product Questions

My Heart Sound Recorder Lecture Series download is missing slides or looks jumbled. Can you help?

The Heart Sound Recorder Lecture Series features text animations to make the show more enticing to watch. The slides have timed animations that play as the presentation plays.

PowerPoint files have two modes: Edit and Play. In Edit mode, the animations won’t play and sometimes cause overlapping text and this is why your slides may appear blank and/or jumbled.

To play the presentation as it was intended, first, unzip the download (using the instructions on the right side of this page), open either file in PowerPoint, select “Slide Show” on the PowerPoint menu bar, and click “Play From Start”. Use the left/right arrow keys or your mouse button to advance the slides. You can also edit the slideshow to play through automatically by changing the animation settings to suit your needs.
