trying to get a good price on a high end pc on the USA/ Vancouver

hey guys

this is my first time in the USA and my first time in Vancouver and I'll be trying to get myself a nice gaming laptop but have heard that a big difference of price may happen based on region. For the next few months, I'll be visiting Alaska, Vancouver, San Francisco, Seattle, San Diego e The Everglades in Florida and would like to know from people who knows the prices around these regions which one is better to buy electronics in general?I think it's worthy of mention that I'll be at the Everglades about 3 times during November and December, kinda close to the Black Friday, hopefully that will give me a better price? Or the prices are affected only during 31th of November and get back to normal right after? Anyways, would love to know where and when it would be the best option to buy it. Thank you very much!
