They don't have the gallons...I guess because no one can afford it. Almost everything they have is shipped in so they have to up the prices...even Wal-Mart. There are tags on the clothing and have a perforated part that you can tear off leaving the tag on so that you can give it to someone as a gift and if it doesn't fit, they can easily return it. Well, in HI, that part of the tag is already removed and a sticker is placed on the tag with the "new" price. Usually 4-5 dollars more.
In today's money, an onion in, say, ancient Judea, would of cost over 1000 dollars, after accounting for inflation and the exchange rate.
