We use random pre-auth and sometimes no pre-auth 0$ for Luxchecker.
The "issue" with allowing to select whether or not to use pre-auth 0$ is that, as you mentioned, some bins will work and some not, which is especially beneficial for cheaters who knows which bins will produce certain error codes that will warrant automatic refunds.
Believe me, cheaters are like ants. Whenever there is the slightest hole, they are very quick to steal everything.
Regarding prices. We have analyzed some major shops, such as "Brian club", where prices are at least double our prices for most bins, and we are well aware that they sell everything incredibly fast.
Another reason why we decided to stick with the current prices is because we have two options;
either sell 1000 cards in bases between 8-10k$ or sell cards for slightly more in our own shop.
This further allowed us to determine the demand for our cards, thus the estimated average price
per card 8-10$, usually depending on the period of the year.
Cards tend to decrease in value towards the end of the year, i.e. those involved in the sniffing-business know that sniffing on web shops on Nov-Dec yield up to 3-4 more times cards vs Jan-June.
Having sold batches for a long period on certain forums before the idea of developing our own shop, have given us a fairly good sense of what pricing we should be looking at this period of the year.

i loaded my account with 50$ to check the quality, what i got was totally live cards! Yeah it's not like other shops I've come across (all dead cards) I bought this shop 4 cards, they work perfectly! But it's not entirely money.

2 cards I bought half an hour ago, I checked through bahira's checker (heard using Luxchecker) and they are valid. After I pay 1 small order about 81 dollars and 2/2 cards, none of them have enough money !
