HP RTX Spark discount (new promo expires at 10/17)

You mentioned going with 128GB, and that's actually a key point: if you're just doing office work and light editing, 128 is enough, but if you plan to run models locally or regularly work on large projects, memory and VRAM are the real bottlenecks, and even a low sale price might lead to quick regret. Also, the stacking order of EPP and Rakuten can sometimes affect cashback tracking, so it's best to confirm before ordering whether each program's terms exclude other offers.

Tax rates and cashback thresholds can vary quite a bit from state to state.

If you're sure you're actually going to buy soon, log into your HP account first and save screenshots of your EPP eligibility and shopping cart, then place the order through the Rakuten entry point so your cashback doesn't get lost. But only do this if you've already compared prices on other channels—don't rush the decision just because a promo is about to expire.

I'm curious—what made you go with 128GB in the end? If someone wanted to add more memory or an external GPU later, what's the upgrade potential like on this model? Also, with the BOA 5% and Rakuten cashback you mentioned, can you actually get both at the same time when placing the order, or do you need to split the order or hit a minimum spend? If they can be stacked, that would be really helpful for people who are still on the fence.
