I used to think that 7-Eleven is everywhere in my home country, However, when i came to Hawaii, now I think ABC stores are my new 7-Eleven.
I definitely agree with many reviewers that ABC Stores are everywhere in Waikiki. They are located almost every block in Waikiki to catch every tourist that walk around Waikiki.
The price is higher than any other mini-marts in Waikiki. Everything is overpriced.
The only thing that has a good deal is
Manoa Lao Machademia Nuts 6 packs for $16.99 which is same price as you can get from other local stores such as Long Drugs.
For tourists, I think ABC Stores is convenience for them to shop. they don't have to get out of Waikiki, they can get all souveniers from ABC Stores. some japanese tourists do not the car, they probably stuck in Waikiki and they think ABC stores have good price for them (compare to Japanese currency).
If you (tourists) have car, i think you should go shop somewhere else such as WalMart, K-mart, Daiei, and Long Drugs... It's a lot cheaper over there.
For locals, I don't think you should shop here! Seriously!
