Ehhhhhh I see what you area saying but you have to take into account that amazon is a conglomeration of things amazon has is in its warehouses and what other companies sell THROUGH amazon. A lot of the stuff that is shooting/hunting related is sold through amazon by someone else. I think this why, when we all look for shooting stuff there aren't crazy deals. Because outside sellers aren't motivated by prime day to drop prices. All that said you just have to know what to look for, amazon more deeply discounts things that are close under their umbrella. I was able score:
A second echo dot which was $15 off already then another $10 credit for voice ordering(with my current echo dot) = $25 Echo dot.
I took a CHANCE on the new amazon fire OS powered Element 55"4K tv for $399 (now OOS) saw it on slick deal slated for sale at 6pm PST sat at my computer and mashed refresh button at 6pm until price dropped from $649 to $399. I say took a "chance" because a number of crappy reviews have come out about this product, but for such a small price I'm willing to bet on amazons return policy and the extended warranty protection of the credit card that I used for purchase.

Then there was/is an Amex promo "amex17prime" with some loop holes (google it) but effectively $30 off $60 = 50% off I bought -9mm collet for my hornady bullet puller -Lee load all II 16 ga conversion -Lee 7/8oz slug mold For 471 Amex meme era hip rewards points and $30

Then I bought the Anova gen 2 wifi 900w sous vide for $129 regular was like $179 a couple days before. Just wanted to screw around with sous vide and this is a palatable price for me given the feature set. I'm going to try and make back my $130 in food prep savings vs buying lunch out at work.

TL;DR Buying shit that amazon is likely to make more money off of reaps better deals
EDIT: formatting, added links, TL;DR
You want to use a transformer rated at 1,000 voltamperes or 1KVA. DO NOT USE those travel converters. They are to be used ONLY on heating only appliances. Like older waffle irons, clothing irons, hair dryers and the like. They produce a poor waveform of current and can damage anything with electronics in it. Like your product. But as you can see from the link, they run about US$100. So unless your have other items you also want to run at 120VAC, it is probably cheaper to buy a new heater in country. For instance in the 1980's I moved for 2 years to England. I bought about 3 transformers, but I brought a number of my US appliances with me.
The only other problem is that they use 50Hz instead of 60Hz. So I also had a frequency converter. I am an electrical engineer and I built that myself. I used it to run my computer monitors and turntable. Both of which would not work correctly on 50Hz, even with the right voltage.
Also what voltage was it rated for? Your product details (click on answered questions, search: voltage) said you could order 120 or 220.
edit: Most modern electronics will work on either 50 or 60Hz without problems. I had old school electronics.
