$2 · Bronze PVC Shrink Capsules for wine bottles

I have approx. 600 of these shrink capsules for wine bottles. They retail for $12.57 for 30 ($11.99 + 12% tax) (see the attached Amazon ad). The retail price for 600 would be $251.40. I am selling them for $2 for 30 or the whole lot for $30 https://www.amazon.ca/Bronze-PVC-Shrink-Capsules-Bag/dp/B009ZUSSBE/ref=asc_df_B009ZUSSBE/?tag=googleshopc0c-20&linkCode=df0&hvadid=293024427005&hvpos=&hvnetw=g&hvrand=12415546029935183353&hvpone=&hvptwo=&hvqmt=&hvdev=c&hvdvcmdl=&hvlocint=&hvlocphy=9001597&hvtargid=pla-568682870549&psc=1
