help with shoes!!!

okay, i am having a tough time with shoes... i bought 2 pairs from sandy's shoes and took them home to show my mom and decide which one. but the more i thought about it, the more i decided i wanted some 'sparkle' to the shoe (rhinestones) on the buckle or something. then as i thought about it more, i decided the heels were too high and i wouldn't feel comfortable. but like a moron, i returned them yesterday without measuring the heel so i don't even know what height to look for when i look online... and i'm having a hard time finding anything i like.
zappos confuses me - how do you find bridal shoes on their website? my glass slipper seems rather expensive. i def don't want to pay more than 100 bucks for shoes. the ones from sandy's were only 55. can anyone help me with other ideas of where to look, either online or in eastern long island (islip area thru port jeff area)?? and how high are your heels? thanks!!
