My mother is being cremated, so I began talking with friends and looking on lines at cremation urns. Most people pay at least $300 for an urn and it can go up into the thousands of dollars. Neither my brother or I are interested in keeping Mom's ashes at home, so we really just needed an urn for burial.
It is not required that you buy an urn from the funeral home. There are many online sellers of urns. The one that I found that had an extensive inventory and the best prices is Mainely Urns. They have something for everyone and their prices are reasonable.
Nowadays even Walmart sells caskets. It is important to plan in advance for your funeral or for the funeral of a loved one. Researching your options will keep you from having to make decisions during a stressful, sad time.
