First purchase.. is this enough? Id not, any links to teach what else needs done? : Carding | Torhoo darknet markets

I am going for a site that has quick shipping, and is not an item commonly carded to be resold.

I have what is claimed to be a $3-5k balance, ill be spending under 300.
I have a socks5 residental with a good score very near the cardholder.

Im using a virtual machine (VPN->VM->SOCKS5)

I want to browse around the site a bit, make an account and spend 30 minuets or so before purchasing. Is this enough time? Im worried the socks5 will die if I wait too long. If I can just use the VPN in the same country, I'll spend an hou or two making an account and browsing. Leave some stuff im not getting in cart, then come back the next day and spend that 30 minuets with the socks5 proxy.

Q1: Will browsing and making annacc with a regular vpn raise any red flags? Or should just do my browsing to look legit 30-60mins before order using the sock5?
Q2: Using a newer browser, what else should/can I do tonlower suspicous activity? Or do I mot meed tonaorry.

Id prefer if I could be linked a guide, but you could also answer the questions directly. Thanks.
