You can still use Etsy's Pin It button, just remove the price text. I also generally remove the price as I think it may turn off a lot of people. If they really like the item, they're going to click on it anyway.
Regarding the article about the pin being included in the "gifts" search if left on the pin, it made me think too. So, I searched "gifts" on Pinterest and VERY FEW of what showed up had the price tag up in the corner. I DID notice, however, that everyone of them had the word "gifts" somewhere in the description of the item.
So, rather than have the price tag in my pins, I'm adding the word "gifts" wherever I can. I'm hoping it will accomplish the same goal without blatantly advertising the price.
