A guy on marketplace is selling Japanese booster packs of:

I wanted to get into pokemon again but I have no idea about these Japanese cards! Are these good/normal prices? Or am I getting played?

I saw someone make a similar comment about a pack here hence why I’m here. If it’s the wrong sub please point me the right way, thank you!

Title says it, but I’d like to know what you base the price on aswel if you wouldn’t mind sharing?:) EU, Netherlands if it helps

I have a few cards here (and more) that I want to sell for a fair price. But I don’t know what rating to consider them or what to base it on?

The 3050 is 99€, the 1660ti is €70. Which one to buy? For gaming and maybe streaming. Low profile both.
