China online purchase strikes again

Im getting tired of having to vent on these BS storefronts online! But let me get it off my chest for your enjoyment.
March 31 I see a smokin deal on a 2Kg tabletop smelter for metals. It has a removeable crucible for the metal as well as the heater element, cheap pair of tongs, unsafe gloves, etc. My son is into this stuff (as well as I) so I thought it would be a cool birthday gift. So I buy it via paypal (oh ****....) and I get a china tracking number. WTF, the guys address is in Arizona? Kinda why I bought it through him....anyway. 15-20 days shipping....MY ***! I kept checking about the 3rd week in and the thing is still parked at the Shanghai airport. A month goes by and it doesn't move! Finally it makes it to Los Angeles and I got it today in the mail after 51 DAYS...'it' was in one of those china bulk mail plastic envelopes that offers no support, but it wasn't a smelter. it was 3 F'n cheap *** 'fashion' face masks!!! The kind that are $3 a piece at 7-11 now. So I paid $70 for 9 buck worth of facemasks? I quickly check the tracking and invoice numbers on the parcel and they all match. So I go back to my paypal records and I see the paid invoice but it only lists a SKU number, invoice number and total paid. So I go back to website and look up this SKU, nothing shows up, all my email correspondence never once mention what I bought, just 'your order'. Im thinking I'm screwed as I have no "not as described" proof that I bought this smelter instead of worthless fashion facemasks as there is no record of the description of the product. I'm thinking there must be a way to see what I bought on March 31...Google to the rescue! >Myactivity.google.com< is a website that allows you to look back in time and see where you were online on a day or timeframe. So Im looking and Bam!, I find the website link that I bought it off of and it even had the hyperlink to the product (still currently for sale at the exact same price as my invoice) and the time I viewed it! Hopefully my inquiry to them to describe to me what I actually bought will shed some light on this predicament. I may have to use this 'proof' with paypal to dispute the 'not as described' buyer protection...These MotherF'rs must think were stupid...maybe we are for still buying crap from them? Tell me how stupid I am.....be gentle.
