jour brought to you by gigante omar's it's seriously has

00:10

everything including a wal mart and target heart Gigantor mart

00:13

is having a sale Prices of all items in the

00:16

store had been reduced by thirty five percent If it's

00:20

shirts on sale for twelve bucks then how much did
