Merchant tab bundle currently excluded from sale

Merchant tabs share the same prices as premium tabs but the merchant tab bundle of 6 tabs is not on sale with all the other stash tabs. I believe its supposed to be 165 coins atm, same as 6 premiums because of sale discount and bundling discount. it has neither of the discounts

I don't think it's a bug lol, but yeah, it would be cool to have it included in the sale.
