Not sure what model you are looking at but was just at Costco tonight. Our local store had the M3 Pro MBP 18/512 for $1499, which is the same price Best Buy had over the weekend
They've been running sales on and off for months trying to clear inventory out for the end of the year. Right now they're still doing back to school on amazon, so I would just hunt around a bit you will find a deal. There's also Black Friday which is more or less around the corner at this point but they usually just do gift cards at apple and maybe $100-200 off I think.
Frankly at this point…..just wait for the M4 models; new OLED screens,
Plus;
The M4 is packed with 28 billion transistors compared to the M3's 25 billion, and it has a memory bandwidth of 120Gbps compared to its predecessor's 100Gbps.
