Personally, I hate BJs, they just don't seem to have as good of a selection as Costco and Sam's Club.
As far as the highchair thing goes, I would save the money and space and buy a booster seat. They are portable when you are visiting friends, they can be put away when friends come to visit, they take up way less space than a high chair, AND they last your child until they are big enough to sit at the table on their own.
By the way: I was born and raised in Baltimore! Still here 25 years later!
