Your question had to be fair enough if this wasn't the bitcointalk.org forum. Most of the times, I've seen users (Not all of them) are trying to belittle newbie users by asking kind of questions with the purpose of ________.
In the fact, at the present, you aren't even a purse.io user. that's why you've pointed out it as,
We currently have Purse.io that as far as I know provides the same service
Which part in my statement did I "belittle" OP? You know what my statement is called? It's called constructive criticism. Look it up. Seriously. It doesn't take an expert to see that. 🤦🏻♂️
Also, I was a past user of Purse.io(not that it actually matters in the first place). The reason I included the "as far as I know" part is because I'm not 100% sure if they still provide the same exact service, as they removed the option to sell products that's not on Amazon.
constructive criticism

don't think about it anyway

. However, I suggest you to go back to purse.io and follow it first. Then, you'll be able to better compare purse.io and Bitstore.tech.
I quit, GL!
