      I ordered a Drirz dress form, at what I thought was a great price, but if it sounds too good to be true, its probably not. When I received a completed order charge from my ****** account, I checked into it. This company had completed the charge without any shipping information. That sent up Red Flags for me, so I contacted them by email, which is the only way of contacting them. I didnt receive a reply. So, then I contacted ****** to file a dispute on the charge. Then to give the company one more chance, I wish I hadnt, because I received an email, from ****** trying to get me to cancel the depute. I contacted ****** this morning, and they never sent the warning to cancel the depute. What kind of company does that. Well, this is a warning to all consumers, please be vigilant when considering to purchase anything from this company.

      Costco claims that they will honor a price adjustment within 30 days of purchase, but will not honor their own digital itemized receipt from their Costco App. On stated app, it shows the date of purchase, the amount paid and that my Costco credit card was used to purchase said items. There is no way to "create" this receipt within their system, so I am having a hard time understanding why they will not honor it. Lesson learned to save all receipts for 30 days in case they decide to put something on sale!
