I am just a lone collector who buys one set of foil lairs for myself and occasionally an extra for friends or to sell as a little personal investment. These are the things that I've learned that might be helpful to get what you want.

It doesn't matter when you enter the pre-drop queue

I've seen a few people think that it helps them get an advantage, but it's all random once the drop starts, doesn't matter if you were first or last in pre-queue

Use different browsers to get more queue spots

I have opera, chrome, and edge all open on my computer, but you can add more if you want

Use as many devices/VPN computer connections as you have access too

I typically have multiple browser apps open on my phone as well as my computer. I also have a VPN for work that my home rig connects too that gives me access to my work computer, so there's another access point for browsers

Incognito/private tabs count as new points of access

Typically access to new queues is limited by browsers, but the incognito/private tabs do not count and give you more chances

All in all, for the stardew valley drop this morning I have 6 queues on my normal desktop, 4 on my phone, and another 4 on my work connection. This lead to a 5min queue where I got what I wanted and I promptly closed the rest of the tabs to give everyone else better chances

Please share any other tips you have out there, just wanted to help how I could. I know it's overboard, but it's not even a few minutes of work to open it all and then you have so many more chances to get what you want
