I ordered a product on a thursday around 4pm. Checked the box for two day delivery, fed-ex. Tracking shows it will not arrive until Tuesday the next week. UPS delivers on weekend, however fed-ex does not. Although the better-braces site says 2 business days, be careful not to pay for two day shipping before a weekend since they use fed-ex as it is wasting money. To same shippers 7 days a week are business days, so know your shippers before spending money for faster delivery. It just might be a little better for customer service to add on their site that business days for fed-ex are not on a weekend.
