MichaelDalke" $5.79 for a pack of 44 Poise #2 pads, before tax. I think there was one of a very rare sale and 0.22 off. Don't know the price of the store brand. Sorry, don't know price of diapers. We get them, it's a necessity, and I don't even look at the price. AK has rather expensive shipping to here, so maybe others in the "lower 48" can tell us their prices.
Alaska has no state sales tax, it is up to local communities. We have, i think, about 3.5% in summer, 2.5% in winter (that's to take advantage of tourists without the locals getting their panties in a twist). Anchorage - biggest city by far - has none (nearly 1/2 the pop. of state) Their property taxes are higher). Ketchikan is about 5%.
Certain things, those not requiring speed like dairy product, and can be shipped in bulk - like cans of soup - might cost 1-3 cents more.
AK used to be 22% more than Washington; then came modern transportation. Better barges and tugs. Containers. Fast cranes to unload containers. Ro-Ro ships
Washington (the state) has 10.1%. Yikes! But non-resturant food is exempt (knowing WA, probably not much else). Not sure what else is exempt. If you are from out-of-state, something you don't consume there is exempt. If I buy a car there, i get a temporary license for Alaska, (The dealer does that) and don't pay the outrageous Washington taxes and fees. Ketchican has a hospital and is too isolated, too small, too close to non-profit, for the hospital they have. They pass bond issues, I don't think any of them lost, and you can see exactly where the money went. A helo-pad for the Medivac helo (It was a half-hour drive from the US Coast Guard base. If you have an ICU patient, seconds can matter). Parking garage. Hyperbolic operating room. Desperately needed improvements for the senior facility wing (that might have one of your grandparents in it). Electrical upgrade. etc. Not too often.
Sales tax is regressive. This site has illustrated that.
