For your wedding supply needs, learn to shop for them at the right time of the year. Since spring and early summer are prime times for weddings, don't shop for your items then. Instead, shop for them during the winter months when prices are lower.
Wedding supply includes your table setting. Do you have enough table cloths, table place settings and the centerpieces that you need? Shop for these all together and get a discount by lumping together the costs. You can do this on the web.
