Thanks for the awesome questions!! Full upvote given!
1. The 1-2% is actually a limitation of Ebaybucks. STORS tokens can be spent for STEEM upvotes or WLS Upshares. While current price of STEEM is low, the FIAT value of an upvote is small. However, we believe that STEEM price can soon exceed all time highs. This means that an upvote FIAT value could well exceed a mere 1-2% cash back. Also, can eBaybucks be sold and bought on an exchange like STORS tokens? No. STORS will be listed on the Bitshares Exchange. **STORS tokens also carry a convertible option in that should dStors Inc. launch an ICO, the STORS tokens can be converted to ICO coins.** Can one convert eBaybucks into Ebay equity shares? No.

2. We are conducting surveys to best identify the most desired product categories within the millennial population. Why? Cryptos are heavily driven by the millennials. We will focus product category catering first to this group. Also, we believe the differentiated incentive model will help boost the traffic to www.dstors.com; we will first start with the STEEM and WLS communities and then grow the merchant and seller populations through word of mouth, visibility campaigns and brand awareness. 

3. Our incentive model is heavily based on the WIIFM (What's In It For Me) principle. This is why the STORS token model which can be spent for lucrative upvotes and upshares is critical and thus differentiating. The reward theory has been proven many times in business models that it stokes the WIIFM to a much higher degree than without. Again, the fact that every STORS token carries a convertible option to trade for an ICO coin is powerfully aimed at the WIIFM. It's almost like having "Founders Options" to a startup company....priceless!

Remember that for eBay too, their very first product sold was a broken laser pointer. They too had a humble beginning. 

Suggestions: Thank you and yes, we will definitely take them into consideration.
