It's the holiday shopping season and in the spirit of the season, everyone loves a good deal. Well, everyone loves a good deal all year long and that's something exchange-traded funds issuers often oblige.

BlackRock's iShares unit, the world's largest ETF sponsor, is adding some cheer to the season, announcing fee cuts on four of its well-known products.

For the most part, the expense ratio reductions are modest, but for long-term investors, those small cuts can add up to big savings over time.

Here are the four iShares ETFs with newly lower fees.

iShares Core MSCI Emerging Markets ETF (IEMG)

The iShares Core MSCI Emerging Markets ETF (NYSE:IEMG) now has an annual fee of 0.11%, or $11 on a $10,000 investment. That draws IEMG to within one basis point of primary rival, the Vanguard FTSE Emerging Markets ETF (NYSE:VWO). VWO and IEMG are the two largest emerging markets ETFs, a competition that's really limited to these two products.

iShares 0-5 Year TIPS Bond ETF (STIP)

There's plenty of debate regarding just how pesky inflation currently is and will be next year, but there's no denying it just got a little bit cheaper to protect against the scourge of rising prices as the iShares 0-5 Year TIPS Bond ETF (NYSE:STIP) now charges 0.05%, down from 0.06%. The $2.91 billion STIP, which turned 10 years old earlier this month, tracks the Bloomberg Barclays U.S. Treasury Inflation-Protected Securities (TIPS) 0-5 Years Index.

iShares Core International Aggregate Bond ETF (IAGG)

The iShares Core International Aggregate Bond ETF (CBOE: IAGG) had its fee trimmed to 0.08% from 0.09%. Alone, that's barely noteworthy, but in this case, it's interesting because IAGG now has the same annual fee as its most director competitor, the Vanguard Total International Bond Index Fund ETF Shares (NASDAQ:BNDX).

iShares International Dividend Growth ETF (IGRO)

Alright, now we're getting somewhere in terms of notable fee reductions. The iShares International Dividend Growth ETF (CBOE: IGRO) is now charging 0.15% per year, down from 0.22%. That's significant by the standards of individual ETF expense ratio reductions.

IGRO's newly cheaper status is relevant for investors heading into 2021 because international stocks are suddenly a favored asset class for the new year and expectations for dividend growth are fairly stout, indicating this ETF could be a fine idea for income investors in the new year.
