The profit margin is lowered because it is shared with the store, but if you think really long term, bringing profit to tue store ensure it stays alive and continues to buy more LeatherMint products.
The store is good for 3 main reasons.
1) It brings legitimacy to the brand
2) It buys in bulk amd makes for lower profit margin but higher gross profit than a single customer
3) offers a place to showcase the products in rral life for people to see and touch
The success of the Bitcoin Bazaar is also mine.
