Would this be tacky?

My husband and I have been going through fertility treatments for 6 years. The only thing we have left to try is <a href="https://glowing.com/glow-fertility-program">IVF</a>, which will be $20k. I'm having a hard time believing we will ever be able to afford it and we're a little desperate to come up with the money.

I have an Etsy shop and I was wondering if it would be tacky to state it in my shop or on each listing, something along the lines of the money from every sale goes toward helping us start our family? Or if I put it on the thank you note I include in the package?

Would you find it tacky or incorporate if you saw that? If not, how should I go about it and word it?
