Robin Good: Charteo is the first slide-by-slide online PowerPoint store offering high-quality, professional-looking slides that can be fully edited and customized. 

Charteo offers more than 10,000 editable business slides, diagrams, charts and maps for Microsoft PowerPoint. Slides can be searched or browsed via a set of well organized categories.

In general, individual slides in Charteo cost apx. 3-4€, but for most you are also offered a large bundle of similar slides for a largely discounted price (e.g. 62 unique 3D slides designs for 49€).

Once you have picked and selected your preferred slides, Charteo packs them all in a .pptx file that sends to you as a link.

I have tested the service and I am impressed by the good quality and assortment of the designs available.

Robin Good: Slidevana has just released its full set of over 150 slide templates for PowerPoint (Mac and PC).

The Slidevana templates collection (which was available until now only for Keynote for Mac) allows anyone who does not graphic design skills to assemble professional-looking presentations by editing directly the content of the sample templates provided in this collection.

While I am not commercially associated with Slidevana, I can only recommend their product as it delivers on its promise, it's fairly priced and it can really save you a lot of time.

In addition, if you are not fully satisfied you can ask for a full refund, and, from my own experience, their customer support service is very good.
