How to Procure Table Linens for Cost Effective Weddings & Events

I have always been astounded at the cost is to rent table Linens.  One option is to buy your linens.  This may sound odd, but you can buy table linens at a fraction of the rental cost.  They will not be as high of quality as the rentals, but once a table is set, I have found that no one notices.  I have samples I show my customer of these low-cost linens.
