Hilo Hatties, Oahu
They ply you with coupons and free trolley rides to get you to come to their stores. I use to really enjoy going to Hilo Hatties in previous visits. Now they are so commerical and over-priced you are better off going elesewhere.
Unique Suggestions: If you have to go to Hilo Hattie's then I would recommend you skip the jewlery and the fashions and go straight away to thier coffees, jams and macadamia nut candies. Though slightly marked up some good bargins can still be had in this department.
Fun Alternatives: Try to visit the Aloha Marketplace which is ocean front shopping and very pleasant to walk around.
