Your eligibility to achieve Silver, Gold, and Platinum status tiers is based on your cumulative eligible purchases made online at www.vietri.com. Your tier status lasts for 12 months following your entry to the tier unless you continue to make additional purchases within those 12 months that meet the threshold of the next highest tier. Conversely, if you make a return that decreases your 12 month cumulative spend below your current tier's threshold, your tier status will be lowered. However, your points do not expire.
