OK..I am a blogger. I am a photographer. I am a retailer. I would NEVER go into someone's store and take photos of their product, unasked. NEVER. As a retailer I don't care if you are a blogger "doing an article". It's rude..and illegal. Please ask the retailer if you can take photos and, like me, they will probably be more than helpful with artists' information etc. But, like me, they do have to protect their artists' product copyright so due credit has to go with a REQUESTED photo. Thank you.
